Domain-to-range ratio

The term "domain-to-range ratio" is not a standard mathematical terminology, but it can be interpreted in a couple of ways depending on the context. In mathematics, the **domain** of a function is the set of all possible input values (usually \(x\) values) that the function can accept, while the **range** is the set of all possible output values (usually \(y\) values) that the function can produce.
