A.0 ≤ x ≤ 2

B.2 ≤ x ≤ 5

C.5 ≤ x ≤ 6

D.6 ≤ x ≤ 8

A.0 ≤ x ≤ 2

B.40 ≤ y ≤ 70

C.5 ≤ x ≤ 8

D.40 ≤ y ≤ 10


C) The linear model represents the height, f(x), of a water balloon thrown off the roof of a building over time, x, measured in seconds. During what interval(s) of the domain is the water balloon's height decreasing the fastest?

A.5 ≤ x ≤ 9.5

B.8 ≤ x ≤ 9.5

C.6 ≤ x ≤ 8

D.5 ≤ x ≤ 6


D) The linear model represents the height, f(x), of a water balloon thrown off the roof of a building over time, x, measured in seconds. Justify your answer from Part C.

A.5 ≤ x ≤ 9.5 is the interval where the balloon's height is decreasing.

B.8 ≤ x ≤ 9.5 is the interval where the slope is the steepest.

C.6 ≤ x ≤ 8 is the interval where the balloon's height decreases the most.

D.5 ≤ x ≤ 6 is the interval where the slope is the steepest.
