## How do you find the vertex of a quadratic equation?

Take the average of r and s to get h = (r + s) / 2 (h is the x-coordinate of the vertex). 3.) Substitute x = h into the quadratic factored form to find y. This will always give us a y-coordinate of k = -a

## How to Find the Vertex of a Parabola

Use the vertex form, y = a(x−h)2 +k y = a ( x - h) 2 + k, to determine the values of a a, h h, and k k. a = −1 a = - 1 h = 3 2 h = 3 2 k = 61 4 k = 61 4 Find the vertex (h,k) ( h, k). (3 2, 61 4) ( 3 2, 61 4)

## What is Vertex Formula? Examples

To do so, we use the following steps: Get the equation in the form y = ax2 + bx + c. Calculate - b / 2 a. This is the x -coordinate of the vertex. To find the y -coordinate of the vertex,
