So the book asks me to sketch out these graphs, and of course there are no examples. I was wondering how this is done.(adsbygoogle = window.adsbygoogle || []).push({});

(a) [0,1] X [1, 2] // The X here stands for the Cartesian product.

(b) ([0,1] U {2}) X [1,2] // How can I graph this? The U stands for Union and the X here stands for the Cartesian Product.

(c) ([0,1] U {2}) X ([1,2] U {3}).// Again, the U stands for Union and the X here stands for the Cartesian Product.
