Unit 3 c 2. Mei next tests her robot's ability to launch tennis balls. A ball's parabolic path through the air can be represented by a quadratic function, where x represents the ball's horizontal distance traveled, and y represents the ball's height above the ground. Part A The robot launches a tennis ball from a height of 4 ft. The ball reaches a maximum height of 40 ft before it begins to fall. It lands on the ground 160 ft from the robot. Mei models this situation with a quadratic function. What is a zero of this function? What is the y-intercept of the graph of the function? Part B Use your findings in Part A to sketch a rough graph of the situation, where y represents the vertical height, in feet, and x represents the horizontal distance, in feet.
