Graph:

\

Graph the equations $\"\"$ and $\"\"$ :

\

Observe the graph:

\

The region is not shaded since there is no common area. \ \

\

Test the solution at point $\"\"$ .

\

Case (i):

\

$\"\"$ (First equation)

\

$\"\"$ (Substitute $\"\"$ )

\

$\"\"$ (Subtract)

\

$\"\"$ (Add)

\

Case (ii):

\

$\"\"$ (Second equation)

\

$\"\"$ (Substitute $\"\"$ )

\

$\"\"$ (Substitute $\"\"$ )

\

$\"\"$ (Subtract)

\

Therefore, the region is not.
