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 …

In other words, the domain is the set of values that we can plug into a function that will result in a real y-value; the range is the set of values that the function takes on as a result of plugging in an x value …

Jul 23, 2025 · Domain: All real numbers except x = 0 (division by zero is undefined). Domain: All non-negative real numbers (x ≥ 0), because you cannot take the square root of a negative number in the …

Domain and range are the main aspects of functions. You can use quarters and one-dollar bills to buy a soda. The machine will not give you any flavor of the soda if pennies are input. Hence, the domain …

Dec 1, 2024 · The domain refers to all the possible values of x (inputs) that a function can accept. Simply put, it’s the set of numbers you can plug into the function without causing any errors.

Functions assign outputs to inputs. 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 …

Dec 3, 2025 · The term domain has (at least) three different meanings in mathematics. The term domain is most commonly used to describe the set of values for which a function (map, transformation, etc.) …

The domain of a function is the set of its possible inputs, i.e., the set of input values where for which the function is defined. In the function machine metaphor, the domain is the set of objects that the …

When graphing, the domain represents the set of x-values for which there are corresponding points on the graph. Example 1: For a polynomial function like f (x) = x² – 5x + 6, the domain is all real …
