In Problems 29 and 30 consider the autonomous differential equation dy/dx = f (y), where the graph of f is given. Use the graph to locate the critical points of each differential equation. Sketch a phase portrait of each differential equation. By hand, sketch typical solution curves in the sub regions in the xy-plane determined by the graphs of the equilibrium solutions.
