15 pts] Sketch some representative solution curves for the autonomous first order differential equation y'- y(2-y) (1 -y). Find all equilibrium solutions, label all pertinent coordinates. Note: An Autonomous equation means that dy/dt does not depend on time t. Hint: Follow the method demonstrated in Example 1.3.6 (p.28). The hand-draw slop field is optional and not necessary. This method gives a qualitative analysis for the future of all possible solutions without solving the equation quantitatively

A bifurcation occurs where the number of equilibrium solutions changes as the parameter varies. As 8 increases, the number of equilibrium solutions changes from two to one and eventually there are none. 4. Solve the equation 0 = yd – 2y + Bfor y in terris of B.
