EXAMPLES Solve the inequality x 2  4x + 12 both graphically and algebraically. Solution: [-2,6] Solve the inequality x 4 > x both graphically and algebraically. Solution: (- ,0)  (1,  )

EXAMPLE Solve the inequality

PHYSICS A ball is thrown vertically upward with an initial velocity of 96 feet per second. The distance s (in feet) of the ball from the ground after t seconds is s = 96t - 16t 2 For what time interval is the ball more than 112 feet above the ground?

PHYSICS Graph the relationship between s and t. What is the maximum height of the ball? After how many seconds does the ball reach a maximum height?
