1. The problem statement, all variables and given/known data If lim (x->0+) f(x) = A and lim (x->0-) f(x) = B Find lim(x->0+) f(x^3-x) 2. Relevant equations 3. The attempt at a solution I'm not sure how to do this. We know the right and left hand limits at x, how is it possible to find the right hand limit at x^3-x?
