In this lesson, you will learn how to find the domain of a rational function with a trinomial denominator. The domain of a function is the set of all possible input values for which the function is defined. When finding the domain of a rational function, you need to determine what values make the denominator zero. To do this, you need to factor the denominator and find the values of x that make it equal to zero. Once you have those values, you can exclude them from the domain.
Finding the domain of a rational function with a trinomial 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.
