If you draw a vertical line anywhere, you should only cross the function at one place.
\n" ); document.write( "This curve passes the vertical line test so it is a function.
\n" ); document.write( "Domain : min to max x values : [-4,2]
\n" ); document.write( "Range : min to max y values : [-3] U (1,4]\r
\n" ); document.write( "\n" ); document.write( "[] - these brackets denote that end values are included.
\n" ); document.write( "() - these brackets denote that end values are not included.
\n" ); document.write( "A U B - means union of A and B.
\n" ); document.write( "
\n" ); document.write( "
\n" );
