Here is a summary of all of the tutorials about rational functions on this site. Struggling with rational functions? These posts should help point you in the right direction! If you’ve got a question about rational functions that I haven’t addressed below, please leave me a comment and I’ll do my best to add the content you request!


All Things Rational

  • In the beginning, there were polynomials. Before you try to conquer rational
    functions, make sure that you have a solid understanding of polynomials.

 

  • Once you’ve mastered polynomials, start with the basics of rational functions. Rational Function Sign PatternLearn about what a rational functions are, how to find the roots, the y-intercept, and the domain. Also learn how to create a sign pattern and use it to solve inequalities!

 

Fully sketched rational function

  • Now that you’ve got the algebra of rational functions figured out, it’s time to dive into graphing. Click here to learn how to put together x- and y-intercepts, vertical asymptotes, horizontal asymptotes, and sign patterns to make great graphs of rational functions.

 

  • Ready to step it up? Learn Rational Function Graphabout how to handle holes in your graph, and what to do if your horizontal asymptote turns out to be slanted.
