The productivity of a country is given by f(x,y) = 13.34x yr, where x is the amount of labor and y is the amount of capital. (A) Find f, (x,y) and fy(x.y). (B) Find f, (63,52) and f, (63,52), and interpret the results. (A) f, (x,y) = (B) The value of f, (63,52) is This means that when there are units of labor and units of capital, a 1-unit increase in (Round to two decimal places as needed.) The value of f,, (63,52) is. This means that when there are units of labor and units of capital, a 1-unit increase in (Round to two decimal places as needed.)
