Consider a firm which uses two inputs, labor (L) and capital (K). The firm's production function is given by f(L,K)=2L+3K. a. 6 points) Draw the firm's isoquant curves for output levels of y= 12 and y = 18. b. (10 points) Now suppose that the input prices are given by W= 1 and wr=2. Suppose that the firm wants to produce 18 units of output. Show graphically the firm's cost minimizing choice of inputs by drawing a graph of the isoquant curve and isocost curves. Explain briefly your answer. C. (4 points) Calculate the cost of producing 18 units of output. d. (5 points) Does the firm's production function exhibit constant, decreasing or increasing returns to scale? Explain your
