Question

Find the average rate of change ​

Answer 1

Answer:

3rd option

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 ] = [ 1, 4 ] , then

f(b) = f(4) = 3³ + 2 = 27 + 2 = 29

f(a) = f(1) = $3^{0}$ + 2 = 1 + 2 = 3 , then

average rate of change = $\frac{29-3}{4-1}$ = $\frac{26}{3}$
