College Algebra · Module 9 · Rational functions and asymptotes

Rational Lab

Build a rational function from its factors and watch the asymptotes, holes and intercepts appear, solve unlimited practice problems with hints and worked solutions, race the clock, and use rational functions on real problems. Nothing here is graded.

Part 1: Asymptote Explorer

Red dashes: vertical asymptotes, with arrows showing where each side goes (left side red-orange, right side green). Purple or orange dashes: horizontal or slant asymptote, with the tails glowing. Open circle: hole.
