"Bill is at tennis practice. He tosses a tennis ball into the air. As the tennis ball comes back down, he decides to hit it back into the air with his racket. Bill notices that the tennis ball hits his racket m seconds after he originally tosses it. As the ball comes back down this time, he decides to catch it. When Bill catches the ball, n seconds have passed since the ball hit his racket. The height of the ball at a given time is h feet." Which of the following functions would best model the situation given above?

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.
