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) = - 4x? - 8xy + 7y The points (x,y), where f(x.y) has a possible relative maximum or minimum are (Type an ordered pair. Use a comma to separate answers as needed.)
