5) The population of rabbits on a small island is modeled by the differential equation time is measured in years. = 1.2P – (3 × 10-4)P², where i) Find all of the fixed points of this equation, and draw a phase diagram. Classify each fixed point as stable or unstable. ii) What is the carrying capacity of the island? iii) Suppose that at t = 0, the population of rabbits is 1000. Find the population as a function of time, and determine when the population will reach 90% of the carrying capacity. (Note: you may refer to the logistic general solution given at the bottom of the page)
