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?
part b: during what interval(s) of the domain is the water balloon's height staying the same?
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.
part d: use the constraints of the real-world situation to predict the height of the water balloon at 10 seconds.
