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 16 seconds. Use complete sentences to support your answer.
