A disc is thrown into the air with an upward velocity of 20 ft/s. Its height h in feet after t seconds is given by the function h=-16t2 + 20t + 6. What is the
maximum height the disc reaches? How long does it take for the disc to reach
the maximum height? How long does it take for the disc to descend to 3 feet
above the ground?

x=30
