select the correct answer jane planted a marigold sapling in her garden and recorded its growth every week. the plants height, in inches, is modeled by the function h(x), where x is the number of weeks since jane planted the sapling x h(x)=3√(7x + 1) 0 3 1 8.49 2 11.62 3 14.07 4 16.16 5 18 what is true of the function as the x - values increase? a. the function is decreasing, but the average rate of change is increasing b. the function is increasing, and the average rate of change is increasing c. the function is decreasing, and the average rate of change is decreasing d. the function is increasing, but the average rate of change is decreasing
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.
