Absolute Value Functions

Absolute Func

When sketching any new graph for the first time, you can use a table of values. A good selection of values is -3 \le x \le 3 but if these don't give enough information, you can find other values.

Another way is to use the definition of absolute values. Look at the example below:

 

Sketch y=\left| x+2 \right|
