Suppose the function g (x) is used to model the height y, of a ball x seconds after the ball is thrown up in the air. Suppose further that a ball reaches its maximum height of 7.5 feet in 5 seconds, and then hits the ground 3 seconds later. What would be an appropriate domain for g (x) ?

Vaughn Kidd · Answer 1

An appropriate domain, values of x on which the function is defined, will be 10 seconds. This is because the graph of g (x) will show change from 0 to 5 seconds, then again show change from 5 to 8 seconds and finally remain flat as no change will take place from 8 to 10 seconds.
