Function domain is the set of all possible values of the argument at which the values of function are defined. I.e. if we are given some function f(x), then its domain is all those values of x which we can input to the equation f(x) and get the result different from infinity and/or division by zero.

Our online calculator (based on the Wolfram Alpha system) is able to find domain for almost any, even very complicated function.
