\fd 3. Given the differential equation F: = 43:1 24y: a) Find the equilibrium solutions (3 points}. b) Use a phase line, for di'erent initial values y(0) = ya, to determine the behavior of the solution curves; i.e. where the solutions are increasing/decreasing (3 points). e) Use another phase line, for different initial values 39(0) = ya, to determine the concavity of the solutions curves (3 points}. d) Sketch the solution curves, using the information above, for the initial values ya = 0J0 = 1J0 = 4,)!0 = 6,35] = 3 (3 points)
