Graph the function (been trying to figure out for nearly 2 hours)

[eaza12]

This is the first question on my assignment, and all the other problems require this graph. I've been trying to figure it out for almost 2 hours now with my partner. Looking for any help we can get. Thanks!

Have you noticed that the Rationals and Irrationals are VERY DENSE?

Just give it a try. Let's see what you get.

… all the other problems require this graph.

Are you sure about that?

Also, were you given the attached image or did you create it? (As posted, it seems like a trick question.)
