Answer:

C. g(x) eventually exceeds f(x) because g(x) is increasing exponentially

Step-by-step explanation:

Comments on the other choices:

A -- an exponential function eventually exceeds any polynomial function. (A linear function is a polynomial of degree 1.)

B -- at x=13, f(x) = 17; g(x) ≈ 18.2, so g(x) is more

D -- over the given interval, the average rate of change of g(x) is about 1/2 (1 unit rise for 2 units run) compared to the slope of 1 that f(x) has.
