4. A model for the population of pigeons in the United States is given by the autonomous DE: Р3 (1— Р)(1 - 2Р)P. To answer the following questions you do not need to solve the DE. points] (a) Find the critical points and phase portrait of the DE. (Portraits without a proper justification for the arrows will get zero credit.) (b) Classify each critical point as asymptotically stable, unstable or semi-stable. (c) Sketch typical solution curves in the regions (in the xy- plane) determined by the graphs of equilibrium solutions.
