DSED Support Question 4 Suppose that the differential equation dy dE = y(40-y) - 300 models a logistic equation with harvesting, where you) represents a spotted grunter population in the Knysna Lagoon at time t, measured in years. Write down the (a) per capita growth rate of the spotted grunter population (b) carrying capacity of the Lagoon. (a rate at which the spotted Lagan grunter are harvested from the Lagoon d) Determine the i criticell points of Eq. (3) (ii) limiting and threshold solutions from Eq. (3) (iii) stability of the critical points by drawing a phase diagram For Eq-(3) e) & Taking y(0) = 11 and a step size b of h=1/12 apply Four iterations of the forward Euler Formula to approximate the solution of Eq. (3). Apply two decinal place rounding where applicable
