Answer:
6
Step-by-step explanation:
Your intervals are x=-2, and x=0. In this case, x=-2 will be a, and x=0 will be b.
To find the average rate of change, you have to first find f(-2) and f(0)

Then, f(0)

Now you know f(-2) is -11, and f(0) is 1.
Next, you plug these into the average rate of change formula, which is

Flug in -11 and 1 on the numerator, and -2 and 0 on the denominator.
