In this lesson I will be teaching you how to graph a rational function. Recall, a rational function is a function that is a variable fraction. This topic takes a little time to master and understand because we have to learn a new concept of something called an “asymptote.” Unlike polynomials or other functions, rational function graphs are more involved and require that you find various points on the graph by using a table. The lesson video will cover it all so no worries! Also, I encourage you to practice graphing these functions with your graphing calculator (like a TI-83) if you have one.
