Given dy/dx = y^2 − 4y + 4
(a) Sketch the phase line (portrait) and classify all of the
critical (equilibrium) points. Use arrows to indicated the flow on
the phase line (away or towards a critical point).
(b) Next to your phase line, sketch the graph of solutions
satisfying the initial conditions: y(0)=0, y(0)=1, y(0)=2, y(0)=3,
y(0)=4.
(c) Find lim y(x) x→∞ for the solution satisfying the inital
condition y(0) = 2.
(d) State the solution to the initial-value...
