1. The problem statement, all variables and given/known data Lim sqrt(r)/(r-9)4 r->9 3. The attempt at a solution I haven't been able to get started on this one I first tried to factor the bottom but I don't know how to or if that is even the right way to solve this problem. I am thinking maybe I have to multiply the bottom out but that seems a bit tedious. is it sufficient to simply test from the left and right in order to get my answer?
