Quick question about logarithms

I'm only in gr.11 right now, and I was looking at a gr.12 textbook, since this isn't really homework I decided to post this here, is that ok or is this the wrong board?

Well anyway, it asked what the range of of the function y = b ^ n would be (and the domain) and also if log(b) n could ever be negative or 0.

Could someone please help?

Err, a correction quickly, it asks the range of y = b^ n and what that means for the domain of log(b) n, it still asks if log(b) n can ever be 0 or negative though.

Oh and an explained answer(not just a one word one) is hoped for.
