Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The average rate of change of h(x) in the closed interval [ a, b ] is
[tex]\frac{h(b)-h(a)}{b-a}[/tex]
Here [ a , b ] = (- 2, 2 ] , thus
h(b) = h(2) = [tex]\frac{1}{8}[/tex] (2)³ - 2² = 1 - 4 = - 3
h(a) = h(- 2) = [tex]\frac{1}{8}[/tex] (- 2)³ - (- 2)² = - 1 - 4 = - 5 , thus
average rate of change = [tex]\frac{-3-(-5)}{2-(-2)}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex]
