Use Lagrange multipliers to find the maximum and minimum values of f subject to the given constraint. Also, find the points at which these extreme values occur. f(x, y, z) = xyz; x² + y² + 2² = 243 The maximum value of f is i The minimum value of f is i The extreme values occur when x = ± MI i .y = ±i and z = ±
