What is the limit of #(x^2-1)/(x-1)# as #x# approaches 1? Precalculus Graphing Rational Functions Limits - End Behavior and Asymptotes 2 Answers GiĆ³ Jul 3, 2018 Answer: I tried this: Explanation: I would try manipulating it: #lim_(x->1)(x^2-1)/(x-1)=lim_(x->1)[cancel((x-1))(x+1)]/cancel((x-1))=2# Jim G. Jul 3, 2018 Answer: #2# Explanation: #lim_(xto1)(x^2-1)/(x-1)# #=lim_(xto1)(cancel((x-1))(x+1))/cancel((x-1))=1+1=2# Related questions What is the limit of the greatest integer function?
