11. (b) Left: s = 2. Right: s = 4. Below: s = 6.

(c) The maximum occurs at about x = .667.

(d) The dynamics remain bounded between 0 and 1 for s between 0 and 6.75.

(e) For s < 4, there is a single fixed point, at x = 0. For s > 4 there are two additional fixed points. The fixed point x = 0 is stable for all s (not just those for which it is the only fixed point). The middle fixed point is always unstable. The right fixed point is stable for 4 < s < 5.33.
