RECIPROCAL FUNCTIONS!

Reciprocal is easy to understand because all it means is A/B becomes B/A. so when a function has a reciprocal all it means is 1/f(x) instead of f(x)/1. Im not sure how to find the asymptotes but i do know that when you know where they are you start the function going the opposite of (lessering/greatering) and do it pointing toward the asymptote without crossing that line...if that makes any sense. it kinda does to me. I just need to figure out how to know where the asymptote of the function is.
