The vertex of h is (–10, –117 and the vertex form is h(x) = (x + 10)² – 117.

What is a function?

A function is an expression that is used to show the relationship between two or more variables.

Given the function:

h(x) = x² + 20x – 17

The vertex is at h'(x) = 0, hence:

h'(x) = 2x + 20 = 0

2x + 20 = 0

x = -10

h(-10) = (-10)² + 20(-10) - 17 = -117

h(x) = x² + 20x – 17

h(x) = x² + 20x + 100 – 17 - 100

h(x) = (x + 10)² – 117

The vertex of h is (–10, –117 and the vertex form is h(x) = (x + 10)² – 117.
