FIGURE 2-4
-Refer to Figure 2-4.Suppose we draw a straight line tangent to point B of the non-linear function.The straight line has a slope of 0.075.What information is conveyed to us by this measurement?

• A)At point B,the marginal response to the application of 30 units of fertilizer per acre is 0.075 tonnes of wheat.
• B)At point B,if one additional unit of fertilizer is applied per acre,the marginal response is 0.075 tonnes of wheat per acre.
• C)Because point B is midway between point A and point C,the yield per acre is 0.075 tonnes of wheat when fertilizer applied is between 10 and 60 units per acre.
• D)At point B,when fertilizer is applied at a rate of 30 units per acre,the yield is 0.075 tonnes per acre.
• E)At point B,the marginal response to the application of 0.075 units of fertilizer is between 4 and 5 tonnes per acre.
