Help me solve the problem pictured.

**PART A:**

Let \( z = f(x, y) = x^2 - y^2 + xy + 2 \).

Consider the triangular region in the \( xy \)-plane with corners at (0,0), (2,0), and (2,2). Find the global max and min of \( f(x, y) \) over this region.

- Show all necessary work including clearly giving and analyzing the one-variable functions above each boundary.
- Type this below: " min = ?, max = ? " Replacing the "?" with the output \( z \)-value of the global min and max.
