we require that \"sqrt%28abs%28x%29-7%29%3E0\"\r
\n" ); document.write( "\n" ); document.write( "this means that\r
\n" ); document.write( "\n" ); document.write( "|x|-7>0
\n" ); document.write( "|x|>7\r
\n" ); document.write( "\n" ); document.write( "so
\n" ); document.write( "(-oo,-7) U (7,oo)
\n" ); document.write( "
\n" );
