Please help? :(

If a projectile is fired straight upward from the ground with an initial speed of 160 feet per second, then its height h in feet after t seconds is given by the function h(t)= -16t^2 + 160t Find the maximum height of the projectile.

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
