a) Consider the cases a < 0, a = 0, and a > 0. In each case find the
critical points, draw the phase line, and determine whether each
critical point is asymptotically stable, semistable, or unstable.
If a > 0, we have the unstable critical point y =
and the asymptotically stable critical point y =
If a < 0, we have the unstable critical point y =
and the asymptotically stable critical point y =
If a = 0, the only critical point y
is Choose one
