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

These examples can be used to construct more functions and find their domains and ranges.

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,andare inverse functions. The domain and range ofareandThese are swapped for the inverse functionso the domain and range areand
