[HURRY] Something about algebraic and analytic functions

[ToC20]

So I have a tough question: Give example of real algebraic functions which is not analytic.

I literally haven't found anything about this from the internet. I have googled a lot and read f.e about transcendental functions etc. I'm getting frustrated.

What is the definition (and properties) of analytic function?
