The graph models the path of a basketball after it was thrown from a player’s hands to the basketball hoop, through the net, and down to the floor. The h values represent the height of the ball in feet above the floor and the d values represent the horizontal distance in feet from the player’s hands. How far from the player does the ball hit the floor?  Make an accurate estimate.  Don’t forget the units. The ball hit the floor _________ from the player.
