Question
16. Find the minimum value of f(x, y, z) = x² + 2y² + 3z?
subject to the constraint x + 2y + 3z = 10. Show that f
%3D
has no maximum value with this constraint.
There is only one critical point, so the minimum value of the function occurs at
Enter your answer in the form:(2/3,7/5,2/9,1/3) with the parentheses, but no spaces.
Note: The fact that we don't have both a maximum and a minimum does not violate the Extreme Value Theorem because the constraint isn't bounded in R^3.
