A Function
The relationship where each input value results in exactly one output value is known as a function. In mathematical terms, a function assigns a unique output to each member of its domain, ensuring that no input corresponds to more than one output. This characteristic distinguishes functions from other types of relations, where an input could potentially map to multiple outputs.

A relation is defined as a function if each input (or domain element) is associated with exactly one output (or range element). In a one-to-many relationship, a single input is linked to multiple outputs, which violates the definition of a function. Therefore, since a function must have a unique output for every input, a one-to-many relationship cannot be classified as a function.

The relationship is called a surjection or a surjective function.
For a relationship to be considered a function, each input value must correspond to exactly one output value. This means that each input cannot have multiple outputs.
A function is any relationship between inputs and outputs in which each input leads to exactly one output. It is possible for a function to have more than one input that yields the same output.

A function is a rule which assigns exactly one output f(x) to every input x.

It is a relationship from one set to another, which is not a function.
