Ryan throws a tennis ball straight up into the air. The ball reaches its maximum height at 2 seconds. The approximate height of the ball x seconds after being thrown is shown in the table.Which equation models the motion of the ball?y = –17(x)(x – 4)y = –16(x)(x – 4)y = –16(x – 2)2 + 68y = –17(x – 2)2 + 68
