Find the average rate of change of an exponential function f (x) over the interval 1 ≤ x ≤ 3.

values of f (x) are shown in the following table.

a. 6

b. 12

c. 24

d. 125/3

Option b. 12

Step-by-step explanation:

we know that

To find the average rate of change, we divide the change in the output value by the change in the input value

The average rate of change is equal to

In this problem we have

Substitute

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
