Hi, I was wondering if I could get an answer to a question that has been bothering me all day today.(adsbygoogle = window.adsbygoogle || []).push({});

Ok, so I got an assignment today and it wants me to find the Critical X's and Local Max/Min points for the equation: y = x/x^2-1

Correct me if I'm wrong on any of this. To find the critical X's I take the derivative and equate it to zero then solve for x to get the critical X's and from there I can find the Max/Min vaules.

After doing that I got x=sqrt(-1). Now I know that is a non real answer, so does that mean that those critical points do not exist? and does that also mean that there is no local max/min points? What exactly does it mean when I get the non real answers for my critical x values. Oh and I also found the critical x's when y is undefined to find the asymptotes.

If i wrote this like crap and you can't understand it, sorry heh, but any feedback is appreciated
