Answer:
Option C
Step-by-step explanation:
The average rate of change of f(x) will be represented by the slope between the given interval [-3, 2]
For x = -3 value of f(x) = -36
and for x = 2 value of f(x) = 4
So there are two points ( -3, -36 ) and ( 2, 4 ) through which function is defined.
Therefore, from the formula of slope =
slope =
= slope =
= 8
Option C is the answer.
