= = 2. This question is about Chain Rules for Many Variables (10 Marks)-Please just choose one from the following two choices to answer. (If you answer both choice A and choice B, the TA will only pick up one to mark) Choice A. Find 24 if z = rh (r, y), with x = 2+s and y = +3 +s?. Choice B. Consider an production function Y F(KL) AKI, where Y is the output, K is capital invested and L is the labor needed. Suppose that K, L are both functions of time t, or K = K (t), L = L(t). In addition, we define Y as the growth rate of output and same as Capital and Labor, then please show that Y = a + Bi. = = = 2.
