Quadratic functions (5 pts) A ball is thrown upward at 40 feet per second from the top of a building that is 30 feet high.
The height of the ball can be modeled by y = 30 + 40x - 16x2 feet where x is the number of
seconds after the ball is thrown. When will the ball first reach a height of 45 feet?
