Question

This table shows values represented by an exponential function.

Answer 1

Answer:

C. 12

Step-by-step explanation:

Average rate of change = $\frac{f(b) - f(a)}{b - a}$

Where,

a = 1, f(a) = 3

b = 3, f(b) = 27

Average rate of change = $\frac{27 - 3}{3 - 1}$

Average rate of change = $\frac{24}{2} = 12$

Average rate of change for the interval from x = 1 to x = 3 is 12
