The domain of a function is the set of values for which the function is defined. When a function is defined by a formula the domain should be an integral part of the definition, although it is often implicit.

For example, the function $f(x)=x^2$ could be defined over:

... and more. In each case the same formula is used, but in each case the function is different.
