    What is the Limit of a Rational Function at a Removable Singularity?

    Homework Statement i think I remember the question to be this: lim (y-3)/(y-3)(y+3) y→3 it was the first limit question and the easiest but I am not sure if I did it right. Homework Equations The Attempt at a Solution so what I did was I canceled the y-3's out to...
