# Vertex Calculator

A Vertex Calculator is a free online tool that displays a vertex of a given expression. STUDYQUERIES’S online vertex calculator tool makes the calculations faster and easier where it shows the vertex point in a fraction of seconds.

## How to Use a Vertex Calculator?

The procedure to use a vertex calculator is as follows. There are two approaches you can take to use our vertex form calculator:

1. The first possibility is to use the vertex form of a quadratic equation;
2. The second option finds the solution of switching from the standard form to the vertex form.

We’ve already described the last one in one of the previous sections. Let’s see what happens for the first one:

• Type the values of parameter a, and the coordinates of the vertex, $$h$$, and $$k$$. Let them be $$a = 0.25,\ h = -17,\ k = -54$$;
• That’s all! As a result, you can see a graph of your quadratic function, together with the points indicating the vertex, y-intercept, and zeros.

Below the chart, you can find the detailed descriptions:

• Both the vertex and standard form of the parabola: $$y = 0.25(x + 17)² – 54$$ and $$y = 0.25x² + 8.5x + 18.25$$ respectively;
• The vertex: $$P = (-17, -54);$$
• The y-intercept: $$Y = (0, 18.25);$$
• The values of the zeros: X₁ = (-31.6969 , 0), X₂ = (-2.3031, 0). In case you’re curious, we round the outcome to five significant figures here.

### What Is Vertex: Definition

Vertex is the point where two or more lines or edges meet to form an angle. In this lesson, you will learn about vertex examples, the vertex definition, and the vertex angle.

Let’s have a look at the two rays: Ray 1 and Ray 2, which originate from the vertex O.

Acute angle geometry: When two rays meet and an angle is formed that is greater than 0 degrees and less than 90 degrees, it is called an acute angle.

As we go forward, you can check out the interactive examples to know more about the lesson and try your hand at solving a few interesting practice questions at the end of the page.

### What Is a Vertex In Triangle?

A vertex in math is a point where two lines or rays meet. An angle is formed at the vertex. A vertex is denoted by uppercase letters like A, O, P, etc.

The plural of vertex is “vertices.” In solid geometry, i.e., three-dimensional geometry, shapes such as cubes, cuboids form several vertices. Let us look at them in detail in the next section.

Look at the triangle DEF.

it has three vertices: D, E, and F that form the angles of the triangle.

### What Is a Vertex In Solid Geometry?

Not just plane shapes, even solid shapes have vertices. In solid shapes, a vertex is formed where edges meet.

Look at this cube,

A, B, C, D, E, F, G, H are the vertices of the cube.

A tetrahedron has 4 vertices. One is marked. Can you identify the other 3 vertices of the tetrahedron?

We can apply Euler’s formula to find the vertices in a solid shape.

Euler’s formula is: $$F + V − E = 2$$

Where,

• F is the number of faces
• V stands for the vertices
• E is the number of edges

### Vertex Of Parabola In Math

In Mathematics, the vertex formula helps to find the vertex coordinate of a parabola, when the graph crosses its axes of symmetry. Generally, the vertex point is represented by $$(h, k)$$. We know that the standard equation of a parabola is $$y=ax^2+bx+c$$ Here, if the coefficient of $$x^2$$ is positive, the vertex should be at the bottom of the U-shaped curve. If the coefficient of $$x^2$$ is negative, then the vertex should be at the top of the U-shaped curve. In this article, we are going to learn the standard form and vertex form of a parabola, the vertex formula, and examples in detail.

#### Vertex Form of Parabola

We know that the standard form of the parabola is $$y=ax^2+bx+c$$

Thus, the vertex form of a parabola is $$y = a(x-h)^2 + k$$

Now, let us discuss the vertex formula in detail.

#### Vertex Formula

The vertex formula is used to find the vertex of a parabola. There are two ways to find the vertex of a parabola.

$$Vertex,\ (h, k) = (\frac{-b}{2a}, \frac{-D}{4a})$$

Where “D” is the discriminant where $$D = b^2 – 4ac$$

“h” and “k” are the coordinates of the vertex.

The above formula can also be written as follows:

$$Vertex=(h,k)=(\frac{−b}{2a},{c−\frac{b^2}{4a}})$$

The other method to find the vertex of a parabola is as follows:

We know that the x-coordinate of a vertex, (i.e) $$h$$ is $$\frac{−b}{2a}$$.

Now, substitute the x-coordinate value in the given standard form of the parabola equation $$y=ax^2+bx+c$$, we will get the y-coordinate of a vertex.

#### Solved Examples Using Vertex Formula

$$\mathbf{\color{red}{Find the vertex of a parabola, y=3x^2+12x-12.}}$$

Given parabola equation: $$y=3x^2+12x-12$$

The given parabola equation is of the standard form $$y=ax^2+bx+c$$

By comparing the given equation and standard form, we get

$$a = 3\ b= 12\ c = -12$$

We know that the vertex formula is $$(\frac{-b}{2a}, \frac{-D}{4a})$$

We know that $$D = b^2 – 4ac$$

Therefore, $$D = 12\times 2-(4\times 3\times (-12))$$

$$D = 144+144$$

$$D = 288$$

Now, substitute all the known values in the formula, we get

$$Vertex,\ (h, k) = (\frac{-12}{2\times 3}, \frac{-288}{4\times 3})$$

$$(h, k) = (\frac{-12}{6}, \frac{-288}{12})$$

$$(h. k) = (-2, -24)$$

$$\mathbf{\color{blue}{The\ vertex\ (h, k)\ of\ the\ parabola\ y=3x^2+12x-12\ is\ (-2, -24)}}$$.

$$\mathbf{\color{red}{Find\ the\ vertex\ of\ the\ parabola\ y=3x^2-6x+1}}$$.

Given parabola equation: $$y = 3x^2-6x+1$$

The standard form of a parabola is $$y=ax^2+bx+c$$

By comparing standard form and given parabola equations, we get $$a = 3,\ b=-6,\ c = 1$$

We know that the formula to calculate the x-coordinate of a vertex is $$\frac{-b}{2a}$$.

## Vertex Form Calculator:

A vertex form calculator is a tool that helps you determine the vertex form of a quadratic equation. For example, if you have a quadratic equation y = 2(x – 3)^2 + 4, you can input the values into the calculator, and it will provide the equation in vertex form, which in this case is y = 2(x – 3)^2 + 4.

## Vertex Calculator With Steps:

A vertex calculator with steps not only calculates the coordinates of the vertex of a quadratic equation but also provides a step-by-step explanation of the process. For example, if you have the quadratic equation y = -2x^2 + 8x – 5, the calculator will show the steps involved in finding the vertex, including identifying the values of a, b, and c, calculating the x-coordinate of the vertex using the formula x = -b / (2a), and then substituting the x-coordinate into the equation to find the y-coordinate.

## Standard To Vertex Form Calculator:

A standard to vertex form calculator is used to convert a quadratic equation from standard form (y = ax^2 + bx + c) to vertex form (y = a(x – h)^2 + k). For example, if you have a quadratic equation y = 2x^2 – 6x + 5, the calculator will perform the necessary calculations and provide the equation in vertex form, which could be y = 2(x – 1.5)^2 + 1.25.

## Axis Of Symmetry And Vertex Calculator:

An axis of symmetry and vertex calculator helps you determine both the axis of symmetry and the coordinates of the vertex of a quadratic equation. For example, if you have a quadratic equation y = -x^2 + 4x – 3, the calculator will determine that the axis of symmetry is x = 2 (which represents the vertical line that divides the parabola into two equal halves) and the vertex is (2, -1) (which represents the highest or lowest point on the parabola).

## Vertex To Standard Form Calculator:

A vertex to standard form calculator is used to convert a quadratic equation from vertex form (y = a(x – h)^2 + k) to standard form (y = ax^2 + bx + c). For example, if you have a quadratic equation y = 3(x – 2)^2 + 4, the calculator will perform the necessary calculations to convert the equation to standard form, which could be y = 3x^2 – 12x + 16.

## Parabola Vertex Calculator:

A parabola vertex calculator helps determine the coordinates of the vertex of a parabola. For example, if you have a parabolic equation y = x^2 – 4x + 3, the calculator will calculate that the vertex of the parabola is at (2, -1), representing the highest or lowest point on the curve.

## Quadratic To Vertex Form Calculator:

A quadratic to vertex form calculator is used to convert a quadratic equation from standard form (y = ax^2 + bx + c) to vertex form (y = a(x – h)^2 + k). For example, if you have a quadratic equation y = -2x^2 + 8x – 7, the calculator will perform the necessary calculations to convert the equation to vertex form, which could be y = -2(x – 2)^2 + 9.

## Vertex Calculator Astrology:

It seems that “Vertex Calculator Astrology” refers to a specific application of a vertex calculator in astrology. In astrology, the vertex is a calculated point that represents a significant turning point or fated encounter in a person’s life. A vertex calculator astrology tool uses the birth date, time, and location to calculate the vertex position and provide insights into significant life events or relationships. However, it’s important to note that astrology is not a scientifically validated field, and the interpretations may vary.
