Discussion Board: Rational Functions

In your initial posting, share with us a resource or tips for working with rational functions when needing to find such things as its domain, range, asymptotes, intercepts, end behaviors, or any other features needing to graph a rational function. Perhaps you have come across a handout or video that covers the steps for graphing a rational function. Tell us also why you chose to share this resource or tips with us.

This is a discussion board not a research paper. Thanks
