P1: (a) Xn+1 = 0.9xn (b) Xn+1 = 2Xn + 2 (c) 3Xn+12X + 1 = 0 P2: P3. (a) f(x) = For each of the following difference equations: Find the general solution. Assume in each case xo = 10. Find lim xn (if it exists). n For each of the following functions: Identify the domain. Evaluate the limit of the function at the discontinuities. If there are no discontinuities, evaluate the limit as x 0. (b) g(x) = For part a above, write the sequence, and plot the X, data for 20 time stops. What pattern do you see? (c) h(x) = x + 4x - 12 X-2 2-x -2 X 3x +4
