The domain of a function
is the set of values of
that can be put into the function to calculate a value of
and the range of the function is the set of values
that the function can take. The domains and ranges of some common functions are given below.

n addition, the domain of the inverse function is the range of the inverse function and the range of the inverse function is the range of the function,
and
are inverse functions. The domain and range ofare
and
These are swapped for the inverse function
so the domain and range are
