3. a) C Solve the differential equation y + 2ty = 4t . (t-4) b) Find f(1) if f(t) is the solution to y y (0) = –4 . y c) |The population of rabbits in a certain forest is observed to grow at a rate proportional to the square root of the population size. (i) Write down the differential equation satisfied by f (t), the population of rabbits in the forest at time t. Your answer should contain an undetermined constant. To receive full credit you must specify the sign of the constant and explain how you know. (ii) Suppose that rabbits start to leave the forest at a constant rate of 50 rabbits per month. Write down the new differential equation satisfied by f (t). d) Given the graph of the function g(y) shown below, use the qualitative theory of autonomous differential equations to sketch on a single graph the solutions to the equation y g(y) corresponding to the initial conditions y(0) = -1 and y(0) = 2.5 . Your graph must include all constant solutions and indicate any points of inflection with a dashed line. zog(4) →y 3.
