How to tell the difference between onto and 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.

    This lesson explains the concept of functions, relations, domain, range, one-to-one, and onto. The concepts are explained using diagrams and example relations. Examples and non-examples of each type of relation / function are shown and explained. This is a great video for learning about the concept of what these terms mean.
