Question
(a) This extreme value problem has a solution with both a maximum value and a minimum value. Use Lagrange multipliers to find the extreme values of the function subject to the given constraint. f(x, y, z) = x2 + y2 + z2, x2 + y2 + z2 + xy = 48 maximum value minimum value (b) Find the extreme values of f subject to both constraints. (If an answer does not exist, enter DNE.) f(x, y, z) = x + y + z; x² = 5, x + y = 4 maximum minimum (c) Find the extreme values of f subject to both constraints. (If an answer does not exist, enter DNE.) f(x, y, z) = yz + xy; xy = 1, y2 + z2 = 81 maximum minimum
