Monica kicks a soccer ball in the gymnasium with all her strength. The relation that models the height of the ball is
h = -0.25x2 + 2.3x, where h is the height of the soccer ball in metres and x is the horizontal distance the ball
travels, in metres. There are lights hung from the ceiling that are 5 meters above the floor. Will the soccer ball hit
any of the lights? If yes, how far away will that light be horizontally from Monica? If not, explain. Show algebraic
work to support your answer. Round final values to 2 decimal places.
