Use Lagrange multipliers to find the point (a, b) on the graph of y = et, where the value ab is as small as possible. P =Find the maximum and minimum values of f (x, y) = 3 + y on the ellipse x2 + 16- = 1 maximum value: minimum value:Use Lagrange multipliers to find the minimum value of the function f(x, y) = x2 + y subject to the constraint xy = 6.
