Lesson Summary:

In this lesson, we learn about one to one functions and the importance of each element in the domain appearing to exactly one element in the range. The teacher uses a numerical subfunction and a graphing analysis to explain the difference between one to one and non-one to one functions. It's emphasized that one to one functions are crucial when talking about inverses, and that every element in the domain must map to a unique element in the range.

Lesson Description:

Overview of one to one functions

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.
