For the function below, find the points where its maxima and minima are at- tained making clear whether the are local or global maxima or minima. Give its maximum and minimum values too. f (x, y, z) = 5x2 + 5y² + 5z2 – 8xy + 6yz – 20 For the function below, find the points where its maxima and minima are at- tained making clear whether the are local or global maxima or minima.
