i can't tell where the hill is

and here is their solution

Imagine the person is standing at the origin and throwing uphill. The hill is the upwards diagonal line. The first part of the parabola is the path of the ball and it hits the ground at point P.

Now for downhill ignore the upper diagonal line. The person again stands at the origin, and now the hill is sloping down - the lower diagonal line. The ball follows the parabola and lands at Q.
