Answer 2

Answer:

B

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

Here a = 1 and b = 3

f(b) = f(3) = 27 ← value of y corresponding to x = 3

f(a) = f(1) = 3 ← value of y corresponding to x = 1, thus

average rate of change = $\frac{27-3}{3-1}$ = $\frac{24}{2}$ = 12 → B
