Suppose the population model (4) is modified to b (a) If show by means of a phase
Chapter 3, Problem 22(choose chapter or problem)
Suppose the population model (4) is modified to b (a) If show by means of a phase portrait (see page 39) that, depending on the initial condition the mathematical model could include a doomsday scenario or an extinction scenario (b) Solve the initial-value problem Show that this model predicts a doomsday for the population in a finite time T. (c) Solve the differential equation in part (b) subject to the initial condition Show that this model predicts extinction for the population as
