Vertex Form

To find the vertex of a parabola in vertex form, look at the constants h and k in the corresponding quadratic equation: y = a (x – h)2 + k This form is easiest to find the vertex from, since all we

Vertex Formula with Solved Examples

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) = (-b/2a, -D/4a) Where “D” is the

What is Vertex Formula? Examples

While the standard quadratic form is a x 2 + b x + c = y, the vertex form of a quadratic equation is y = a ( x − h) 2 + k. In both forms, y is the y -coordinate, x is the x -coordinate, and a is the constant that tells you whether

How to Find Vertex of a Parabola?

To find the vertex of a parabola, you first need to find x (or y, if your parabola is sideways) through the formula for the axis of symmetry. Then, you’ll use that value to solve for y (or x if your parabola opens to the side) by using

How to Find the Vertex of a Quadratic Equation: 10 Steps

Finding the Vertex of a Parabola with a Simple Formula 1 Find the x coordinate of the vertex directly. When the equation of your parabola can be written as y = ax^2 + bx + c, the x of the vertex can be found using the formula x = -b / 2a. Simply plug the a and b values from your equation into this formula to find x . See more
