Hi all, I'm wondering whether an expression which is used to describe a function in a certain domain is a different function for the same expression with a differing domain.(adsbygoogle = window.adsbygoogle || []).push({});

For example: expression; x^2.

f(x) = x^2 for domain {1 < x < 10}

f(x) = x^2 for domain {10 < x < 11}

Are these two f(x)'s the same function, or different functions, by definition. I couldn't be sure by Wikipedia, and it's a difficult question to type into a search engine.
