Question

A. 12 B. 6 C. -6 D. -12

Answer 1

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, b ] = [ 2, 4 ]

f(b) = f(4) = 16 ← from graph

f(a) = f(2) = 4 ← from graph

average rate of change = $\frac{16-4}{4-2}$ = $\frac{12}{2}$ = 6
