In this lesson, we learn about going from relationships to functions. We start by understanding the relationship between two coordinate points and the special kind of relationship they share. We then move on to understanding input and output variables, domain and range, and how they relate to each other. The special thing about a function relationship is that every x value is related to a specific output value, making it a unique and easily identifiable relationship. We are given examples of both functions and non-functions to help solidify our understanding.
Going from relations to 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.
