2) The function f : R3 - R is a continuous function that is differentiable at any point except (1, 1, 0) and X C R' is a compact set. We are given that: . The gradient of f is equal to the zero vector only at the points (0, 1, 2) and (3, 2, 1) and both of these points are interior points of X. . f(0, 1, 2) =3 and f(3, 2, 1) = 1 . (1, 1, 0) is an element of X. Given this information, what can you say about the minimizers of f over the set X? Does a minimizer exit? If a minimizer exists, where can it be? You should state the most that you can about the minimizers of f over X given the information. Given an explanation to your claim
