The coordinates are $\"\"$ and $\"\"$ .

Draw a coordinate plane.

Plot the points.

The function is even function.

Even functions are functions that are symmetric with respect to the $\"\"$ - axis.

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

The symmetric points with respect to origin are $\"\"$ and $\"\"$ .

Above points are also on the graph.
