Consider the following autonomous DE. y' 4(y-1)2(y-3) Choose all correct answers. There are two critical points. If y(1) = 4, then the solution is an increasing function. One critical point is semi-stable. y = 3 is a solution. One critical point is a repeller. If y(0) = 2, then lim y(x) = 3 X- One critical point is an attractor.
