checking relative extrema

[Dorian Gray]

Hello once again Math friends,

I apologize for posting another question so quickly after a previous one, but like the other problem, my problem isn't matching up with my answer key (and thanks to Galactus for confirming it).




Please let me know if you get the same answer as me, or if you spot an error in my work.


I got my relative minimum to be (0,-1).
