Consider the graph below, which shows the path of a basketball shot toward a basket. Here, the x-coordinate is the distance the ball is from the player, measured in feet, and the y-coordinate is the height of the ball, also measured in feet. From the graph, determine all the x-values for which the basketball is 15 feet above the ground. a.) 6 ft and 23.5 ft b.) 8 ft and 23.5 ft c.) 6 ft and 19 ft d.) 5 ft and 22 ft
