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 + y° +z? = 27 The maximum value of f is i The minimum value off is i The extreme values occur when x = +± -y = + and z = +

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 + z? = 27
The maximum value of f is i
The minimum value off is i
The extreme values occur when x = ±
i
-y = ±
and z = +
