1. The problem statement, all variables and given/known data Given the function Study its continuity 2. Relevant equations 3. The attempt at a solution I don't know how to solve this function. Normally I'd try to prove the limit doesn't exist by getting different results trough different ways. However, in this function I don't have a point where the continuity might or might not exist. I have a conjunct of points. Can anyone give me a hint on how to solve this?
