A baseball player throws a ball from the outfield toward home plate. The ball's height above the ground is modeled by the equation y = –16x^2 + 48x + 6, where y represents height, in feet, and x represents time, in seconds. The ball is initially thrown from a height of 6 feet. This is the maximum height that the ball reaches.
