3) Suppose f (x, y) is a differentiable function. a) If (a, b) is a critical point of f (y) (in the sense that or (a, b)-0,(a,b)-0 will (a, b) be a critical point of g(x, y) = (f(x, y)) ? b) if (a, b) is a critical point of 9 (x, y) = (f(x, y))², in the sense that (a,b) = 0,(a, b) = 0, will (a, b) be a critical point of f(x,y)? hint: how are the partial derivatives of f(x,y) and 9 (x,y) related?
