4432550672What is the average rate of change for this function for the interval from x = 3to x = 5?O A. 10B. 25C. 32D. 16

Answer 1

We can find the average rate of change using the following formula:

`\begin{gathered} r=(f(b)-f(a))/(b-a) \\ \end{gathered}`

Where:

`\begin{gathered} a=3 \\ b=5 \\ f(a)=f(3)=18 \\ f(b)=f(5)=50 \end{gathered}`

Therefore:

`r=(50-18)/(5-3)=(32)/(2)=16`

Answer:

D. 16
