WebSep 5, 2015 · Sorry if it wasn't clear. Usually you just draw a dot (i.e. a point) at the point 3 on your number line. If you needed to represent { 2 } ∪ ( 4, ∞), then you could use a filled-in dot for individual points, so you might draw something like the following: As Alex G. mentioned, since 3 is in ( 2, ∞), { 3 } ∪ ( 2, ∞) = ( 2, ∞) so you ... WebIn interval notation, the domain would be [1975, 2008] and the range would be about [180, 2010].
