For a Simple Graph of a Production Function with Q

Multiple Choice

For a simple graph of a production function with Q on the y-axis and L on the x-axis, which of the following statements is true?

A) The slope of the production function at a specific point equals the marginal product of labor whereas the average slope of the production function equals the average product of labor.
B) The average product of labor is equal to the slope of the ray from the origin to the apex of the production function for all values of L.
C) The slope of the production function at a specific point equals the marginal product of labor whereas the slope between the origin and a specific point on the production function equals the average product of labor.
D) The average product of labor is never equal to the slope of the ray from the origin to the apex of the production function.
