A softball is tossed into the air upward from a first floor balcony. The distance of the ball above the ground at any time is given by the function, h(t)=14+32t-16t² , where h(t) is the height of the softball above the ground (in feet) and t is the time (in seconds). What was the maximum height, in feet, of the softball above the ground after it was thrown?
