Question

When do you use a Vertex Form y=a(x – h)2 + k ? What information do you get from a Vertex Form?

Answer 1

The vertex

Explanation:

Vertex form shows you the vertex of a quadratic equation.

the y coordinate of the point is determined by k.

the x coordinate is determined by:

(x-h)=0

x-h=0

+h +h

x=h
