Lesson Summary:

In this lesson on Characteristics of Rational Functions, the instructor explains how to identify the vertical and horizontal asymptotes, slant asymptotes and x and y intercepts for a given function. Starting with finding the x and y intercepts, the instructor then explains how to identify the vertical asymptote, and how to determine if a horizontal asymptote exists. The instructor then goes on to explain how to identify a slant asymptote and how to graph it. Overall, this lesson provides a comprehensive understanding of how to identify the different characteristics of rational functions.

Lesson Description:

How to find the vertical,horizontal,slat asymptote and x and y intercepts

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.

Questions answered by this video:
  • How do you determine the x-intercept ?
  • How would you calculate the y-intercept?
  • Why doesn't the function have a horizontal asymptote?
  • How would you know when a function has a slant asymptote?
  • How do you find the slant asymptote?

    It's a good revision of x-intercept, y-intercept, horizontal and vertical asymptotes. We are also told how to determine the slant asymptote? However I would have preferred if the conventional long division was used to actually find the slant asymptote
