Consider the modified logistic population model where P0?) is the population at time t. (a) For what values of P is the population in equilibrium? (b) For what values of P is the population increasing? (c) For what values of P is the population decreasing? Locate the bifurcation values for a: for the one-parameter family d: (1: : :92 +3y+au Locate the bifurcation values for a. for the one-parameter family
