Consider the following short-run production function: q = 5 - 1/3 . At what level of L do diminishing marginal returns begin? At what level of L do diminishing returns begin?

What will be an ideal response?

MP = 10L - . Marginal product peaks when L = 5 and equals zero when L = 10. Thus diminishing marginal returns begin when L = 5, and diminishing returns begin when L = 10.
