What is the Average Rate of Change of a Function?

The formula for the average rate of change is, f(b) - f(a) / b - a.

Given the following:

a = 12, f(a) = -36
b = 18, f(b) = 0

Average rate of change = 0 - (-36) / 18 - 12

Average rate of change = 36 / 6

Average rate of change = 6

Approximate average rate of change would be: A. 5.92 dollars per month
