1-101.

Rewrite as a piecewise function using two linear equations. Describe how the graph changes. .

Start by sketching a graph. If you do not know what looks like, graph

*, then...*

How would the absolute value sign change this function?

Notice that is the boundary point of

*. So the piecewise function will have two pieces that meet at*

*. The first piece looks like*

*_______ and the second piece looks like*

*___________.*

Use the eTool below to view the graphs of the function.
