Carla, Rachel, and Jack each throw a baseball into the air. Carla's baseball's height is represented in the graph below. The vertical axis represents the ball's height in feet, and the horizontal axis represents time in seconds. Rachel recorded the height of her baseball each second after her throw in the table below. The height of Jack's baseball is represented by the function h(1) =- x2 + 5x + 6, where h(t) is the height of the ball in feet after t seconds.​
