12) to show that: (a) If -1 < A < 0, then limn-+oo pen) = B II - A. (b) If A < -1, then p(n) is unbounded. I (c) If A = -1, then pen) takes only two values: if n is even, p(o) pen) = 2B I-A pO) = - - - Po if n is odd. 11. Supposethatthe supply and demand equations are given by D(n) 3 and Sen + 1) = p2(n) + 1. = -2p(nH (a) Assuming that the market price is the price at which supply equals demand, find a difference equation that relates pen + 1) to p(n). (b) Find the positive equilibrium value of this equation.

To demonstrate that F4 has at least 2k periodic points of period k (including periodic points of periods that are divisions of k). 2. ] + I) = 4 x(n)[1 - x(n)]. 3. 1). Show that: (i) For 1 < /L S 3, x* is an attracting fixed point. (ii) For /L > 3, x* is a repelling fixed point. 4. Prove that lim n ..... oo F~ (x) = ! if 0 < x < 1. 6 The Logistic Equation and Bifurcation 43 5. 6. I). Show that if x* < x < ~, then Iim n ..... oc F;(x) = x*. 6. 1, < I + -/6. 7. 6). 1, = 1+-/6. 8. 54 using a calculator or a computer.

7a. Asymptotically stable equilibrium price. I. ___. 7b. Stable equilibrium price. (iii) In case (c), prices osci11ate infinitely about the equilibrium point p* but progressively move further away from it. 7c). 3, Problem 9). 12) This explicit solution allows us to restate cases (a) and (b) as follows. , ms < md), the market wi11 then be stable. If the suppliers are more sensitive than the consumers, the market will be unstable. 12) by using a computer algebra program, such as Maple.
