A Function

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

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.
