A linear function f (x, y) = ax + by + c has no critical points. Therefore, the global minimum and maximum values of f (x, y) on a closed and bounded domain must occur on the boundary of the domain. Furthermore, it can be easily seen that if the domain is a polygon, then the global minimum and maximum values of ƒ must occur at a vertex of the polygon. Find the global minimum and maximum values of f (x, y) = 5x – 8y - 1 on the domain where |x| + |y| ≤ 2. (Give your answers as a whole numbers.)
