Question:
In Exercises, find all points (x, y) where f (x, y) has a possible relative maximum or minimum. Then, use the second-derivative test to determine, if possible, the nature of f (x, y) at each of these points. If the second-derivative test is inconclusive, so state.
f (x, y) = x2 + 3xy + 4y2 - 13x - 30y + 12
