Suppose a firm employs capital (K) and labor (L) to produce a product with the following production function: Q = min(K, L), where Q is the quantity produced and min(K, L) is the minimum (i.e., smallest) value of K or L. For example, if K = 20 and L = 30, then Q = 20 (since the smallest value of K or L at this combination is 20); if K = 30 and L = 20, then Q = 20 (since the smallest value of K or L at this combination is 20); if K = L = 20, then Q = 20 (since both K and L have the same value, making the smallest value 20 at this combination).
A. Graph the isoquant corresponding to Q = 20.
