Answer

Answer:

D. The function is increasing, but the average rate of change is decreasing

Explanation:

Step1: Check function trend

As (x) goes from (0) to (5), (h(x)) values go from (3) to (18), so the function is increasing.

Step2: Calculate average rate of change

For (x = 0) to (x = 1), average rate of change (=\frac{h(1)-h(0)}{1 - 0}=\frac{8.49 - 3}{1}=5.49). For (x = 4) to (x = 5), average rate of change (=\frac{h(5)-h(4)}{5 - 4}=\frac{18 - 16.16}{1}=1.84). Since (5.49>1.84), average rate of change is decreasing.
