Solve the problem.The motion of an imaginary ball bouncing along a flat, level surface, such that each bounce is identical in peak height and horizontal velocity to the bounce before it, is modeled by the following functional relationship between the instantaneous height, f(x), of the ball above the flat surface and the horizontal position, x, of the ball along the surface:
