Math 2 word problem

Question

Calvin kicked a soccer ball laying on the ground. It was in the air for 5 seconds before it hit the ground. While the soccer ball was in the air it reached a height of approximately 25 feet. Assuming that the soccer ball’s height (in feet) is a function of time (in seconds), what is the range in the context of this problem?

Answer 1

Since the ball’s height is a a function of time we can write this mathematically as

f(t) = height where t is the time

The range of function are it’s possible y-values, thus in this function all the possible heights. The soccerball starts off at the ground (y=0) and goes to a maximum height of 25 ft (y =25). This would give the range of the function as [0,25]

(Note: Brackets are used because the ball DID start at the ground and DID reach 25ft making these values inclusive in the range)
