Determining if a set of ordered pairs is a function
In this lesson, you will learn how to determine if a set of ordered pairs is a function or not. The key is to ensure that everything in set A maps to something in set B, and that each input value maps to a unique output value. If a single input value maps to multiple output values, the relationship is not a function. By following these rules, you can easily determine whether a set of ordered pairs is a function or not.
Determine if an ordered pair is a function or not
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 video shows 3 examples matching elements from one set with elements of a second set. The instructor explains which relationships represent functions, and which do not.
