\

All possible values of $\"\"$ is the domain of a function.

\

The domain is $\"\"$ or $\"\"$ .

\

Range is the corresponding $\"\"$ values of the function for different values of $\"\"$ .

\

The range is $\"\"$ or $\"\"$ .

\

If the graph is symmetric about $\"\"$ -axis, then it is an even function.

\

If the graph is symmetric about origin, then it is an odd function.

\

Observe the graph of the function.

\

The graph is symmetric about $\"\"$ -axis, thus it is an even function.
