SOMEONE, PLEASE HELP

Describe how to determine the average rate of change between x = 1 and x = 3 for the function f(x) = 3x3 + 1. Include the average rate of change in your answer.

39

Step-by-step explanation:

The rate of change is found by

f(x2) -f(x1)

x2 -x1

x2 is 3 and x1 is 1

f(3) = 3 x^3 +1 = 3(3)^3 +1 81+1 =82

f(1) = 3(1)^3 +1 = 3+1 =4

82 -4

3-1

78

2

39

39

Step-by-step explanation:

Find the function values for the given x

Subtract to get the change in f(x)

Divide by the change in x

f(3) = 3(3)³ + 1 = 82

f(1) = 3(1)³ + 1 = 4

Average rate of change:

(82 - 4)/(3 - 1)

78/2

39
