# How To Find The Vertex Of A Quadratic Function?

Parabolas always have a lowest point (or a highest point, if the parabola is upside-down).

This point, where the parabola changes direction, is called the “vertex”.

If the quadratic is written in the form y = a(x – h)2 + k, then the vertex is the point (h, k).

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

We find the vertex of a quadratic equation with the following steps:

• Get the equation in the form y = ax2 + bx + c.
• Calculate -b / 2a. This is the x-coordinate of the vertex.
• To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.

## What is the vertex formula?

y = a(x – h)2 + k, where (h, k) is the vertex. in y = ax2 + bx + c (that is, both a’s have exactly the same value).
