This lesson focuses on determining the asymptotes of a rational function. The teacher first shows how to find the vertical asymptote by setting the bottom of the equation equal to zero. The domain of the function is also discussed, as it is closely related to the vertical asymptote. Next, the teacher explains the rules for finding the horizontal asymptote, based on the degrees of the polynomials in the equation. The three rules are: if M is equal to N, divide the coefficients of the leading terms, if M is less than N, the horizontal asymptote is 0, and if M is greater than N, there is no horizontal asymptote.
Determining the asymptotes of a 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.
