The domain of a function is the set of values for which the function is defined. Since produces a real number for any real number value of , in other words, is real for all real , the domain is the set of all real numbers.

Contrast this with . Since the value 1 would make the denominator be zero, is not defined at , so the domain here is all real numbers such that .

Consider . is not defined in the reals for any value of x that is negative, so the domain of is the set of all real numbers such that .

See?

Good luck and happy holidays.
