WILL MARK BRAINLIEST! NEED HELP! 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.

147

Step-by-step explanation:

The average rate of change is found by

f(x2) - f(x1)

x2 -x1

Let x2 be 5 and x1 be 3

f(x2) = f(5) = 3 *5^3 +2 = 3*125 +2 = 375+2 = 377

f(x1) = f(3) = 3 *3^3 +2 = 3*27 +2 = 81+2 = 83

Substituting into the equation

377 - 83

5-3
