The total cost function is TC = Q3 - 6Q2 + 14Q + 75. When does diminishing returns to production set in?

What will be an ideal response?


The marginal cost curve is 3Q2 - 12Q + 14 and the first derivative of the MC curve is 6Q - 12 so if set to zero to find the minimum and the point where diminishing returns sets in the result is 6Q - 12 = 0 and 6Q = 12 so Q = 2.
