An online vertex form calculator helps you to find the vertex of a parabola and the vertex form of a quadratic equation. This vertex calculator quickly displays vertex and y-intercept points with a graph. Also, you can find how to find the vertex, quadratic to vertex form, and vertex to standard form conversions in the context below.

Letâ€™s start with some basics!

In the conic section, the vertex form of a parabola is a point or place where it turns, it is also known as a turning point. If the quadratic function converts to vertex form, then the vertex is (h, k).

The vertex equation is

$$ y = a(x â€“ h)^2 + k $$

The vertex of a parabola is a specific point that represents the different values of the quadratic curve. The vertex can be either maximum (when parabola going downward) or minimum (when parabola going up). Therefore, the vertex form is the intersection of a parabola with its symmetric axis.

Normally, the vertex is (h, k), where h indicates the x-coordinates, and k stands for y-coordinates.

A standard form of a parabola \( ax^2 + bx + c \), so we can use quadratic equations of the vertex coordinates:

$$ h = -b / 2a $$

$$ k = c â€“ b^2 / 4a $$

However, an Online Parabola Calculator helps to find the standard form and vertex form of a parabola equation for the given values.

**Example:**

Finding the vertex of a parabola for the equation:

$$ = 2(x â€“ (-6))^2 â€“ 13 $$

**Solution:**

According to given equation

Vertex form is:

$$ y = 2 (x + 6)^2 â€“ 13 $$

Standard form of given equation is:

$$ y = 2 x^2 + 24 x + 59 $$

Where,

Characteristic Points are:

Vertex P (-6, -13)

Y-intercept P (0, 59)

An online parabola vertex calculator can display a parabola graph with exact values when you substitute the same values for a vertex form equation.

The standard form of a quadratic equation is \( m = a x^2 + b x + c \), where m and x are variables and a, b, and c are the coefficients. It is simple to solve an equation when it is in standard form because we calculate the answer with a, b, and c. However, when you need a graph of a parabola, quadratic function. The process is smooth when the equation is in vertex form. The standard to vertex form of a quadratic equation is \( Q = m(x â€“ h)^2 + K \), where m represents the slope. Our standard form to vertex form calculator can change the standard to vertex form. If you want to do it manually then follow these instructions:

- Write the standard form of a quadratic function: \( m = a x^2 + b x + c \).
- Divide first two terms by a: \( m = a (x^2 + b/a x) + c \).
- Complete the square for the expression with x. Then, add and subtract \( (b/(2a))^2 \) from the equation: \( m = a [ x^2 + x (b/a) + (b/(2a))^2 – (b/(2a))^2] + c\).
- Now, according to square formula, we can say write: \( m = a [(x + (b/(2a))^2 – (b/(2a))^2] + c \) and multiply the terms with a: \( m = a (x + (b/(2a))^2 â€“ b^2/4a + c \).
- Then compare the vertex equation: \( m = a (x â€“ h)^2 + K \) , the vertex of parabola is: \( h = – b / 2a and k = c â€“ b^2 / 4a \).

However, an Online Slope Calculator helps to find the slope (m) or gradient between two points in the Cartesian coordinate plane.

A free online vertex form calculator can convert vertex form to the standard form of a parabola. If you want to know how to change the vertex to standard form, letâ€™s start!

- Write an equation in vertex form: \( m = a (x â€“ h)^2 + K. \)
- Now, expand the square formula: \( m = a (x^2 + y^2 + 2hx) + K. \)
- Multiply the inner side or bracket: \( a x^2 + a y^2 + 2 ahx + K. \)
- Then, compare with quadratic form of a parabola: \( m = a x^2 + b x + c. \)
- Estimate the values of parameter: \( b = – 2 ah and c = a h^2 + k \).

This vertex calculator can convert the standard form to vertex form or vertex to standard form with these steps:

- Now, the calculator displays an equation according to the selected option.
- Then, substitute the value of variables according to the equation.
- Click the calculate button to see the conversion and vertex points.

- This vertex of a parabola calculator displays a vertex and standard form of the given equation.
- This calculator also provides characteristic points with a parabola graph.

The vertex of an angle is the endpoint of two different rays that form the angle.

A common vertex is shared by two angles. A vertex is a point of intersection where two linear construction lines intersect each other.

A turning point of a line or function is a point where fâ€²(x)=0. A turning point is a point where the parabola is upward (from decreasing to increasing) and fâ€²(x)=0 at the point.

First, find the zeros (0) by any factoring or the Quadratic Formula method. Now, find the x of the vertex by averaging the zeros. Then, we can calculate the f(x) to find out the y-coordinate of a vertex.

Use this vertex form calculator to find the vertex and y-intercept points of the given equation. A special form of a quadratic function is a vertex form. With a vertex form, we can see where the point of the parabola is maximum or minimum.
