A special relationship where each input has a single output is known as a function in mathematics. In this context, each element from the domain (input) is paired with exactly one element in the codomain (output), ensuring a unique output for every input. This property distinguishes functions from other types of relationships, where an input might correspond to multiple outputs. Functions are commonly represented using equations, graphs, or tables.
Returns to scale refer to a special relationship between output and input. During production, this relationship refers to the connection between the changes that occur with the output and those that began in the input.

There need not be any relationship.
The relationship between work input and work output is defined by the efficiency of a system. Efficiency is a measure of how well a system converts input work into output work and is calculated as the ratio of output work to input work. A higher efficiency indicates a more effective conversion of work input to work output.
input
A function.
The relationship between the input of 4 and the output of 32 suggests a multiplicative rule. Specifically, it appears that the output is 8 times the input (4 × 8 = 32). Therefore, the rule can be expressed as: output = input × 8.

Design
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.
