Are endpoints also critical points?

I'm trying to find the critical points of a function on the interval [-1,5]. So far,the only critical point I have is 2. Does that mean -1 and 5 are also critical points?

only if it is horizontal there.

I hope it was not you who posted this earlier, where I explained it all.

Yeah, how dare I ask for clarification on something I'm trying to understand.
