As a phase line, use a U-shaped curve. Let its downward-sloping segment intersect the 45 degree line at point L, and let its upward-sloping segment intersect the 45 line at point R. Answer the following five questions: (a) Is this a case of multiple equilibria? (b) If the initial value y0 lies to the left of L, what kind of time path will be obtained? (c) What if the initial value lies between Land R? (d) What if the initial value lies to the right of R? (e) What can you conclude about the dynamic stability of equilibrium at L and at R, respectively?
