Step-by-step explanation:

Step 1: Define

g(x) = x³ - 4

h(x) = x² + 2

h(-2) is x = -2

g(-1) is x = -1

Step 2: Find h(-2) - g(-1)

Substitute:                    ((-2)² + 2) - ((-1)³ - 4)Exponents:                   (4 + 2) - (-1 - 4)Add/Subtract:               6 - (-5)Subtract:                       11
