How to graph absolute value functions using standard form

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 shows you how to start with the parent absolute value function and use this to apply transformations and obtain new graphs. The vertex is found and the slope is used to give a rough sketch of the two example functions. This is a great tutorial for how to graph absolute value functions without a table of values.
