Question

Using the following figure, find the average rate of change of f for 2

Answer 1

3

Explanation:

The average rate of change from x = a to x = b is:

average rate of change = [f(b) - f(a)]/(b - a)

Here we have a = 2; b = 3.

f(a) = f(2) = 2.4; f(b) = f(3) = 5.4.

average rate of change = (5.4 - 2.4)/(3 - 2) = 3
