An autonomous differential equation has the following equilibrium solutions: y = 7, unstable y = -4, semistable Find the limit of the solution as t -> oo, for the following initial conditions: (a) If y(0) = -1, then lime-, y(t) = (b) Ify(0) = -13, then lim + y(t) = (c) If y(0) = 7, then lim, too y(t)
