Plot the total, marginal, and average products and explain in
detail the relationship between each pair of curves. Explain why
marginal product first rises, then declines, and ultimately becomes
negative. What bearing does the law of diminishing returns have on
short-run costs? Be specific. “When marginal product is rising,
marginal cost is failing. And when marginal product is diminishing.
Marginal cost is rising.” Illustrate and explain graphically.
