4.4 Suppose that a firm has a fixed-proportions production function, in which one unit of output is produced using one worker and two units of capital.

If the firm has an extra worker and no more capital, it still can produce only one unit of output.

Similarly, one more unit of capital does the firm no good.

a. Draw the isoquants for this production function.

b. Draw the total product, average product, and marginal product of labor curves (you will probably want to use two diagrams) for this production function.
