\n" ); document.write( "What I mean is that well in the problem there is a graph and there are some black circles(points, ordered pairs) and then there are some white circles(points, ordered pairs) outlined in black...do i find the domain for all of those points? (im sorry if my question doesnt make any sense but any advice is helpful)

If the black circles are the endpoints of a line segment
\n" ); document.write( "the entire interval is part of the domain.
\n" ); document.write( "--------------
\n" ); document.write( "If a point has an open circle around it that value is
\n" ); document.write( "excluded from the domain.
\n" ); document.write( "-----------------
