Just a question in general, when a theres a problem like this "Use graphs and tables to find the limit and identify any vertical asymptotes of the function.

limit of 1/(x-1)^2 as x approaches 1" the answer is always "the limit does not exist" how do you go about finding the limit? I know the vertical asymptote is 1 obviously, but is the limit Negative infinity? and if so, why
