(2) There exists a path satisfying an iso curve function f(x, y), where f(x, y) = d and d is a given value. The function f (x, y) is defined for any value of x and positive y. The following are partial derivatives of f (x, y): af (2, y) = fm(2, y) = 12e32 (12 - 2y), af (2, y) = fy(x, y) = besty. ay Assume that the implicit function y = g(x) is defined by the isoquant (that is, the iso curve) and that the derivative of g(x) exists. Find the analytical form of g(x) that passes through the point (0, 5)
