Graphing a Rational Function with a Trinomial Denominator
In this lesson, we learn how to graph a rational function with a trinomial denominator. The first step is to find the vertical asymptote, which is where the denominator equals zero. The graph will approach the asymptote but never touch it. The next step is to find the horizontal asymptote, which is determined by comparing the degrees of the numerator and denominator. The x and y intercepts are also found, and then a table of values is created by plugging in different x values. Plotting these points and connecting them with a smooth curve produces the graph of the rational function.

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
