The height (h) in feet of a ball (t) seconds after being tossed upward is given by the function h(t) = 72t - 12t². 27. How can we solve the maximum height that the ball will reach? A. Calculate using the formula -b/2a
B. Calculate the value of h as 3, plug 3 into the equation for t
C. Calculate the value of h as 6, plug 6 into the equation for t
D. Factor out -8, then factor the remaining equation, then switch the signs or use quadratic formula
