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 supp
Part D: Use the constraints of the real-world situation to predict the height of the water balloon at 14 seconds. Use complete senter
