Describe how to determine the average rate of change between x = 3 and x = 5 for the function f(x) = 3x3 + 2. Include the average rate of change in your answer.

Average rate of change = 147

Step-by-step explanation:

Given:

x = 3, x = 5

f(x) = 3x³ + 2

Find:

Average rate of change

Computation:

x = 3

f(x) = 3x³ + 2

f(3) = 3(3)³ + 2

f(3) = 83

x = 5

f(x) = 3x³ + 2

f(5) = 3(5)³ + 2

f(5) = 377

Average rate of change = [377-83] / [5-3]

Average rate of change = [294] / [2]

Average rate of change = 147
