Asymptotes & Rational Functions
Rational functions are basically just giant fractions with one polynomial divided by another, but they're a bummer to graph because there's so much to keep track of: horizontal asymptotes, vertical asymptotes, slant asymptotes (oblique asymptotes), x-intercepts, y-intercepts, zeros... In other words, these are a grab bag of everything you've ever seen this whole year. You even have to factor! And making them scarier is that on the test teachers often put full-page problems with 5 parts asking you to break these down every which way! Not fun, certainly, and very time-consuming; but it really is five separate questions, and I'll show you how to get through them one at a time.
