Question

How do the values of a, h, k, and c affect the appearance of a parabola in

vertex form?

Answer 1

This is the vertex form of a parabola.

f(x) = a(x - h)² + k

a will cause a vertical stretch or shrink

h will shift the vertex to the right or left

k will shift the vertex up or down

I am not familiar with what c is.
