I'm not sure if I'm doing the problem wrong or the answers are wrong. I plug in the points to both differential equations but none seem to be critical points.

I'm not quite sure how to do that ...? I just plugged in each point to both differential equations and I didn't get that they equaled zero, which is the definition of a critical point right? When the derivative is equal to zero?

I'm not sure exactly how you'd like me to show that? All I have is scratch paper?

I've plugged in all five points to both equations multiple times and still cannot get it.
