Answer:
Choice B; The average rate of change of f is the same as g.
Explanation:
The average rate of change of a function f(x) over an interval [a, b] is defined as
[tex]m_{avg}=\frac{f(a)-f(b)}{a-b}[/tex]
Now in our case for f(x) over [3, 5]. Since f(3) = 59 and f(5) = 71, the average rate of change in the above equation becomes
[tex]M_{avg}=\frac{71-59}{5-3}=6[/tex]
