And another:

Answer 3

So, in the first solution, I'm unsure of how one can say that in the stable condition, that solutions below y1 approach y1. It seems to be a negative slope, and values seem to be decreasing.

In the second solution, I'm just quite unsure of what they're getting at and forming conclusions.
