You want the expression under the radical to be greater than or equal to zero. which means:
\n" ); document.write( "2x+7 >= 0
\n" ); document.write( "2x >= -7
\n" ); document.write( "x >= -7/2
\n" ); document.write( ".
\n" ); document.write( "In interval notation:
\n" ); document.write( "[-7/2, +oo)
\n" ); document.write( "where
\n" ); document.write( "oo means infinity
\n" ); document.write( " \n" ); document.write( "

\n" );
