A-Math: How to Sketch Modulus Graph [video]


Modulus Graph Sketching_Page_01

This morning, I received an email from a student on asking how to draw a modulus graph with and without boundary condition.

What is boundary condition?
It is usually the range of values of x (otherwise known as domain) for the graph.

Though I have written a similar post in 2009 here, I feel that a video will show you clearly the step by step and important points to consider. Note that my drawing isn't perfect, afterall it's a freehand draw on my tablet, so you got to bear with my 'not so straight' lines :)

The video is about 7 minutes long. Around 6min 30s, I've included a bonus question to challenge yourself. Go ahead and answer it on the comment section.
