If the production function is f (x1, x2) minx1, x2, then the cost function is c(w1, w2, y) minw1, w2y.

The provided statement seems to contain formatting errors and does not accurately describe the relationship between a production function and a cost function. Typically, a production function is expressed as $f(x_1,x_2)$ to represent the output based on inputs $x_1$ and $x_2$ . The cost function, generally denoted as $c(w_1,w_2,y)$ , is derived from the production function and represents the minimum cost of producing output $y$ given input prices $w_1$ and $w_2$ , but it does not directly mirror the format of the production function as suggested.
