Increasing Nature of the Production Function

Fixed Inputs and Diminishing Marginal Product

General Production Function of a Farmer (y=g(h))

A production function describes the relationship between a variable input (X) and the resulting total output (Y), for non-negative values of X. For this relationship to be economically plausible, it must satisfy two key conditions: 1) Zero input results in zero output, and any positive input yields a positive output. 2) The function must be consistently increasing, meaning more input always leads to more output. Based on these conditions, which of the following mathematical expressions could NOT represent a plausible production function?

Plausibility of a Production Model

A relationship between a single input (X) and total output (Y) must meet two core conditions to be considered an economically plausible production model: 1) Output is zero if input is zero, and positive for any positive input. 2) Output consistently increases as input increases. Analyze each mathematical function below (assuming X ≥ 0) and match it to the description that correctly explains its plausibility.

Plausibility of a Proposed Production Function

Consider a production process where the relationship between a single input (X, where X ≥ 0) and total output (Y) is described by the equation Y = -X² + 10X. This equation represents a plausible production function for all positive values of input X because it shows that adding more input initially leads to a significant increase in output.

Critique of a Proposed Production Model

A production process is described by the relationship between a single input (X) and the total output (Y), where X ≥ 0. For this relationship to be considered a viable model of production, it must satisfy two fundamental properties: 1) no input produces no output, and any positive amount of input produces a positive amount of output; 2) the total output must consistently rise as more input is used. Given these properties, which of the following equations represents a plausible production function for all positive values of the input?
