A competitive firm uses a single input x to produce its output y. The firm’s production function is given by y = x3/2 for quantities of x between 0 and 4. For quantities of a greater than 4, the firm’s output is y = 4 + x. If the price of the output y is $1 and the price of the input x is $3, how much x should the firm use to maximize its profit?
answer is 0.
