WRT x-axis:
\n" ); document.write( " $\"x%5E4+-+%28-y%29%5E4+=+16+=+x%5E4+-+y%5E4\"$ , so YES.
\n" ); document.write( "WRT y-axis:
\n" ); document.write( " $\"%28-x%29%5E4+-+y%5E4+=+16+=+x%5E4+-+y%5E4\"$ , so YES.
\n" ); document.write( "WRT origin:
\n" ); document.write( " $\"%28-x%29%5E4+-+%28-y%29%5E4+=+16+=+x%5E4+-+y%5E4\"$ , so YES. \n" ); document.write( "
