Move the letters a, h, k to modify the shape of the line so that it looks like a parabola. Try to shape the parabola so that it lays directly onto the half strobe. Guestimate the coordinate point of the basketball hoop. After you have finished modifying your parabola, check the quadratic equation where it says "c". Use this equation to solve for x by setting it equal to the y coordinate of the point of the hoop. If both sides equal, then the basketball goes directly through the hoop. If not the ball misses.
