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.

Relation
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.
The constant of proportionality can be calculated by dividing the output variable by the input variable in a proportional relationship. It represents the ratio between the input and output quantities in the relationship. This constant remains the same throughout the relationship.
