A farmer's output (y) is determined by the hours of labor (h) they input, according to a production function y = g(h). A realistic production function should exhibit two key properties for any positive number of hours worked (h > 0):

1. Output increases as more hours are worked.
2. Each additional hour of work adds less to the total output than the previous hour.

Which of the following algebraic forms for g(h) correctly models both of these properties?

Verifying Production Function Properties

A farmer's output (y) is related to the hours of labor (h) they provide, where h > 0. Different mathematical models can be used to represent this relationship. Match each mathematical model below with the economic property it describes.

Consider a production process where output (y) is determined by the hours of labor (h) according to the function y = 20h - 0.5h², for h > 0. This production function accurately models a scenario with both increasing output and diminishing marginal returns for all positive values of labor input.

A production process is modeled by the function y = 10 * h^b, where y is the total output, h is the hours of labor (h > 0), and b is a positive constant. For this model to accurately represent a situation with diminishing marginal returns, the value of b must be less than ____.

Bakery Production Analysis

A student wants to mathematically verify that a given production function, which relates output to a single input, exhibits two key properties: 1) output always increases as the input increases, and 2) each additional unit of input adds less to the total output than the previous unit. Arrange the following mathematical steps in the correct logical order to perform this verification.

A production process is modeled by the function y = 10 * ln(h + 1), where y is the total output and h represents the hours of labor (h ≥ 0). To algebraically verify that this process exhibits positive but diminishing marginal returns, one must examine the function's first and second derivatives with respect to h. Which of the following statements correctly interprets the signs of these derivatives for all h > 0?
