This is really nit-picky, but could you flip the colors of the lines on the graphs so that the blue parabolas are f(x) and the red parabolas are g(x)? Red is the first thing the eye picks up, so the tendency is to view the red line as the variable that changes (as opposed to the fixed variable). Since the blue parabolas are the functions that result from changes to the red parabola, the red parabola serves as a constant here.
