Answer:
[tex]m = 324[/tex]
Step-by-step explanation:
The average rate of change is:
[tex]m = \frac{h(2)-h(-2)}{2 - (-2)}[/tex]
[tex]h(-2) = 81\cdot (-2)^{3}-(-2)^{2}[/tex]
[tex]h(-2) = -652[/tex]
[tex]h(2) = 81\cdot (2)^{3}-(2)^{2}[/tex]
[tex]h(2) = 644[/tex]
[tex]m = \frac{644-(-652)}{2-(-2)}[/tex]
[tex]m = 324[/tex]
