In this lesson, you will learn how to find the domain of a rational function with a root as the denominator. The domain is all the values that are defined for your function, so you can't have input values that don't give an output value. You'll see how to apply this thinking to a function and learn how to solve for values that make the denominator 0, as well as the inequality that the radical function has to be greater than 0. By the end of the lesson, you'll know how to determine the domain for a rational function with a root as the denominator.

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.
