Concept:The production function shows how a firm turns physical inputs into physical outputs.
Explanation:It expresses the maximum output obtainable from given quantities of inputs.
For example, the production function is written as
q=f(L,K).
Here,
q is the quantity of output, while
L and
K represent the inputs of labour and capital.
This relationship is purely technical because it deals with physical quantities, not money values or market conditions.
Therefore, the correct option is the production function.
