Chapter 5, Problem 80(choose chapter or problem)
An explosion causes debris to rise vertically. The function f(t) = -16t 2 + 72t describes the height of the debris above the ground, f(t), in feet, t seconds after the explosion. a. Find and interpret f(2). b. Find and interpret f(4.5). c. Factor the polynomial -16t 2 + 72t and write the function in factored form. d. Use the factored form of the function to find f(2) and f(4.5). Do you get the same answers as you did in parts (a) and (b)? If so, does
