Dec 11, 2025 · A function represents a relationship between a set of inputs (domain) and their corresponding outputs (range), where each input has exactly one output. Domain: The set of …

In its simplest form the domain is all the values that go into a function, and the range is all the values that come out.

Domain refers to input values and range refers to output values generated by the function. Learn how to find the domain and range of a function along with many examples and graphs.

Simple explanation for domain and range. We learn the domain of a function is the set of possible x-values and the range is the resulting set of y-values.

All of the values that can go into a relation or function (input) are called the domain. All of the values that come out of a relation or function (output) are called the range.

In mathematical terms, given a function f (x), the values that f (x) can take on constitute the range of the function, while all the possible x values constitute the domain.

A function's domain is where the function lives, where it starts from; its range is where it travels, where it goes to. Just like the old cowboy song!
