How would you graph ##y = ln(x^2) ## without a calculator?

I tried with a....simplification...!

I would try using the base of the natural log (which is the irrational number ##e=2.71828##) as being ##3##. This is a huge simplification but it helps to make things easier for us.

So basically I would graph:

##y=log_3(x^2)##

Where the "real" graph is:

graph{ln(x^2) [-10, 10, -5, 5]}
