\

The equation is $\"\"$ .

\

Observe the graph:

\

The equation $\"\"$ is symmetric with respect to the $\"\"$ - axis, $\"\"$ - axis and origin.

\

\

Numerical support :

\

Symmetry about $\"\"$ - axis is $\"\"$ .

\

Observe the point $\"\"$ is on the graph and $\"\"$ is also on the graph.

\

The graph is symmetric with respect to the $\"\"$ - axis.

\

\

Symmetry about $\"\"$ - axis is $\"\"$ .

\

Observe the point $\"\"$ is on the graph and $\"\"$ is also on the graph.

\

The graph is symmetric with respect to the $\"\"$ - axis.

\

\

Symmetry about origin is $\"\"$ .

\

Observe the point $\"\"$ is on the graph and $\"\"$ is also on the graph.

\

The graph is symmetric with respect to the origin.

\

\

Test algebraically :

\

Test algebraically symmetric with respect to the $\"\"$ - axis.

\

Substitute $\"\"$ for $\"\"$ in $\"\"$ .

\

$\"\"$

\

$\"\"$

\

Because $\"\"$ is equivalent to $\"\"$ , the equation is symmetric with respect to $\"\"$ - axis.

\

\

Test algebraically symmetric with respect to the $\"\"$ -axis.

\

Substitute $\"\"$ for $\"\"$ in $\"\"$ .

\

$\"\"$

\

$\"\"$

\

Because $\"\"$ is equivalent to $\"\"$ , the equation is symmetric with respect to $\"\"$ - axis.

\

\

Test algebraically symmetric with respect to the origin.

\

Substitute $\"\"$ for $\"\"$ and $\"\"$ for $\"\"$ in $\"\"$ .

\

$\"\"$

\

$\"\"$

\

Because $\"\"$ is equivalent to $\"\"$ , the equation is symmetric with respect to the origin.

\

\

The equation $\"\"$ is symmetric with respect to the $\"\"$ - axis, $\"\"$ - axis and origin.
