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:
part a: during what interval(s) of the domain is the water balloon's height increasing? (2 points)
part b: during what interval(s) of the domain is the water balloon's height staying the same? (2 points)
part c: during what interval(s) of the domain is the water balloon's height decreasing the fastest? use complete sentences to support your answer. (3 points)
part d: use the constraints of the real-world situation to predict the height of the water balloon at 14 seconds. use complete sentences to support your answer. (3 points)
