Answer:
A). interval 0 ≤ x ≤ 2
B). interval 2 ≤ x ≤ 4
C). interval 8 ≤ x ≤ 10
D). h(14) = 0
Step-by-step explanation:
Part A.
In the interval 0 ≤ x ≤ 2, height of the water balloon is increasing.
Part B.
In the interval 2 ≤ x ≤ 4, height of the water balloon is constant.
Part C.
In the interval 8 ≤ x ≤ 10, height of the water balloon is decreasing the fastest.
Slope of the line between x = 8 and x = 10 is the maximum.
Part D.
Since at x = 10 height of the water balloon is h = 0, therefore, at any moment after x = 10 seconds height of the balloon will remain zero.
