OK, that works.
\n" ); document.write( "The domain is all the x values where the function is defined.
\n" ); document.write( "( $\"2\"$ , $\"5\"$ ]U( $\"5\"$ , $\"7\"$ ]=( $\"2\"$ , $\"7\"$ ]
\n" ); document.write( "where \"(\" means it doesn't include the endpoint and \"]\" means it does include the endpoint.
