Solve the problem.A projectile is fired straight upward. The function 
describes the height of the projectile, f(t), in feet, t seconds after firing. Factor the polynomial 
and write the function in factored form. Use the factored form of the function to find f(2).
A. f(t) = -8t(2t - 7); 48 ft B. f(t) = -8t(2t - 7); 80 ft C. f(t) = t(-16t + 56); 48 ft D. f(t) = t(-16t + 56); 80 ft
