Similar to polynomials, you need to know where rational functions are increasing and decreasing in order to properly graph them. In addition, you also need to know the domain, since it no longer necessarily consists of all real numbers. In this video, Katie describes how to find horizontal asymptotes, vertical asymptotes, and holes.
