The cost function c(w1, w2, y) of a firm gives the cost of producing units of output when the wage of factor 1 is w1 and the wage of factor 2 is w2. Find the cost functions for the following firms: A firm with production function f(x1,x2) = min{ 2xl,3x2} A firm with production function f(xl,x2) = 2x1 +3x2 A firm with production function f(x1,x2) = In
