8 0

Answer:

Step-by-step explanation:

Given the equation h(x) = 2x²

To solve for h(-2) + 5 then, we need to break the problem into two parts

First, we will solve for the function h(x) at x = -2

h(x) = 2x² so

h(-2) = 2(-2)²

h(-2) = 8

Knowing this, we can plug 8 into our original expression for h(-2)

8 + 5

This gives us 13
