In this lesson, you will learn about the difference between onto and one-to-one functions. A function is a relation where each element in the domain pairs with one element in the range. A one-to-one function is where every element in the domain has a unique pairing with an element in the range. An onto function is where every element in the range is paired with an element in the domain. Through various examples and non-examples, this lesson will help you understand the concepts of onto and one-to-one functions.
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.
