For the equation on the right
x = -â1 should actually be written as x=â(-1)
Hence it is an imaginary value and therefore there is no vertical asymptote
In this lesson, the instructor explains how to find the vertical and horizontal asymptotes of an equation. To find the vertical asymptote, set the denominator to zero and solve for x. If there is no solution, then there is no vertical asymptote. To find the horizontal asymptote, compare the degrees of the numerator and denominator. If the degree of the numerator is less than the degree of the denominator, then the horizontal asymptote is y = 0. If the degrees are equal, then the horizontal asymptote is the ratio of the coefficients of the highest degree terms.

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.
