Use Lagrange multipliers to find the possible maximum or minimum points on that part of the surface z x y for which y x 5 x 2 Then use your calculator to sketch the curve y x 5 x 2 and the level curves to the surface f(x, y) x y and show that the points you have just found do not represent relative maxima or minima What do you conclude from this observation

Question: Use Lagrange multipliers to find the possible maximum or minimum points on that part of the surface z = x y for which y

Use Lagrange multipliers to find the possible maximum or minimum points on that part of the surface z = x − y for which y = x⁵ + x − 2. Then use your calculator to sketch the curve y = x⁵ + x − 2 and the level curves to the surface f(x, y) = x − y and show that the points you have just found do not represent relative maxima or minima. What do you conclude from this observation?
