Domain → Function → Range. Example: when the function f (x) = x 2 is given the values x = {1,2,3,...} then those values are the domain. Domain, Range and Codomain. Illustrated definition of Domain of a Function: All the values that go into a function. The output values are called the range.
The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

The domain of a function includes all real input values that would not cause us to attempt an undefined mathematical operation, such as dividing by zero or taking the square root of a negative number. The domain of a function can be determined by listing the input values of a set of ordered pairs.
In mathematics, the domain of a function is the set of inputs accepted by the function. It is sometimes denoted by or , where f is the function. In layman's terms, the domain of a function can generally be thought of as "what x can be". [1] More precisely, given a function , the domain of f is X.
The domain and range of a function is all the possible values of the independent variable, x, for which y is defined. The range of a function is all the possible values of the dependent variable y.
Domain: The function. f(x) = x 2 + 2 . is defined for all real values of x (because there are no restrictions on the value of x). Hence, the domain of `f(x)` is "all real values of x". Range: Since x 2 is never negative, x 2 + 2 is never less than `2` Hence, the range of `f(x)` is "all real numbers `f(x) ≥ 2`".
When we identify limitations on the inputs and outputs of a function, we are determining the domain and range of the function. Definitions: Domain and Range. Domain: The set of possible input values to a function. Range: The set of possible output values of a function.
