5) Find the absolute maximum and absolute minimum values of f(x, y)
and all points (x,y) at which they occur on the set D = {(x, y): x² + y² ≤ 4}.
-x²-y² (x² + 2y²)
6) Use Lagrange multipliers to find the maximum and minimum values and points (x,y,z) at
which they occur, of f(x, y, z) = x² + 2y² + 3z² subject to the constraints x + y + z = 1 and
x -y + 2z = 2.
