Part A
1) x intercept represents when the ball is on the ground.
2) Max value represents the highest height that the ball can reach, which is 15 feet.
3) Interval that is increasing : when the distance goes from 0 feet to 10 feet. (The ball is going up)
4) Interval that is decreasing : when the distance goes from 10 feet to 20 feet. (The ball is coming down)
Part B
At distance = 12, height = 14
At distance = 15, height = 11
Change in distance = 15 - 12 = 3 feet
Change in height = 14 - 11 = 3 feet
Average change = 1 feet height per 1 feet distance
This represents the rate of deceleration.
