Let f(x)=lnx−(x−1) and g(x)=x2−1. Consider the limit
x→1limg(x)f(x).
Determine whether the conditions needed to replace this limit with the limit of the ratio f′(x)/g′(x) at x=1 are satisfied. Respond with “yes” or “no,” and justify your answer by stating the relevant function values and derivative value(s) at x=1.
