What is the average rate of change for this function for the interval from x=3 to x=5?

timofeeve [1]

Answer:

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 ] = [ 3, 5 ]

From the table of values

f(b) = f(5) = 32

f(a) = f(3) = 8

Hence

average rate of change = $\frac{32-8}{5-3}$ = $\frac{24}{2}$ = 12
