Domain of f in algebra. In mathematics the domain or set of departure of a function is the set into which all of the input of the function is constrained to fall. The domain of a function is the set of all possible inputs for the function. F x 1 f x 1.

The domain of the expression is all real numbers except where the expression is undefined. The answer is no since latex left infty 3 right latex is a proper subset of the domain of latex f circ g latex. X x r x x ℝ.

This means the domain of latex f circ g latex is the same as the domain of latex g latex namely latex left infty 3 right latex. Since a function is defined on its entire domain its domain coincides with its domain of definition. We can also define special functions whose domains are more limited.

For example the domain of f x x is all real numbers and the domain of g x 1 x is all real numbers except for x 0. X y and is alternatively denoted as. Set builder notation.
