Writing Piecewise Functions
In this lesson, you'll learn how to write a piecewise function from a given graph. The instructor breaks down the process into three steps: determining the three equations for the different lines on the graph, finding the constraints for each equation, and putting it all together in a piecewise function format. By the end of the lesson, you'll be able to take any graph and write it out as a piecewise function with ease.
How to write a piecewise function from a given graph
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.

Staff Review
This lesson shows how to write a piecewise function when given a graph. Each part of the function definition is written out from the graph. There are 3 different behaviors for the function in 3 different intervals. This is a great lesson for first learning how to write the equations of a piecewise function.
