Graphing Rational Functions in the form of y = a/(x - h) + k

Author: Dan Bowler

1. To review some vocabulary associated with hyperbolas

2. To learn to graph a hyperbola using its asymptotes as a guide.

This lesson uses a video to demonstrate how to graph a hyperbola which is centered at some point other than the origin. It then provides two practice problems so that students can check their understanding of the concept.
