Cobweb parabola. Mindscapes 30 − 32 describe cobweb plots that involve a parabola with equation y = 4 x ( 1 − x ) . As described there, this parabola opens downward (“sad-face”) and intersects the x-axis at x = 0 and x = 1. Explain how these points of intersection can be found simply by setting y = 0 and solving for x .
