What are domains and ranges in math? (URGENT HELP NEEDED)?

I think the domain is all of the possible inputs for a function, and the range is all of the outputs, but I am not sure and I have a huge test tomorrow (3-12-11).

For example, for the function f(x)=a(x+1)+5, if a <_x <_a+4, all of the x values would be the domain and the results would be the range, right?

Please explain in as simple terms as possible. (P.S. "<_" is supposed to be equal to or greater than)
