\n" ); document.write( "\n" ); document.write( "If you have a parentheses mark, you make a little circle (meaning the endpoint is NOT included). If you have a bracket, you make a solid dot (meaning the endpoint IS included). Once you have the endpoints marked, you make a heavy line between the endpoints.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "For your problem b: Make a solid dot at -1 because you have a square bracket on that end, make a little circle at 8 because you have a parentheses on that end, make a heavy line between the solid dot and the little circle to show that ALL of the numbers between the endpoints are included.\r

\n" ); document.write( "\n" ); document.write( "You should be able to figure out the rest.\r
