After finding the domain, the teacher said that you did not have to write x does not equal -3 because -3 is greater than -5. However, because -3 is greater than -5, you DO have to write x does not equal -3. So the domain is all real numbers >= -5 but not equal to -3.

Lesson Description:

Here I show how to find the implied domain

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.

    This is a good lesson showing how to express the domain of a function and find the values that either make the function undefined or make the function non-real.
