2) Let w31n(w + b) + b2y = (21) + y + w)3. a) (30%) Can we think of b as a function of y and to around point Q = (b,y,w) = (1,0, 2)? Answer this question by checking Whether the two conditions in the Implicit Function Theorem are satisfied. b) (70%) Find the expressions for 819/83; and 812/811} and evaluate them at
