# Please explain how can I solve 25, 29, and 35. /> Attachment 1 Attachment 2 ATTACHMENT PREVIEW Download attachment IMG_0489.jpeg Find all points (x, y) where f(x, y) has a possible relative maxi- mum or minimum. Then, use the second-derivative test to deter- mine, if possible, the nature of f(x, y) at each of these points. If the second-derivative test is inconclusive, so state. V25. f(x, y) = -5x2 + 4xy - 17y2 - 6x + 6y+2 26. f(x, y) = -2x2 + 6xy - 17y2 - 4x + 6y 27. f(x, y) = 3x2 + 8xy - 3yz + 2x + 6y 28. f ( x, y ) = 8xy + 8y2 - 2x + 2y -1 29. f (x, y) = x4 - x2 - 2xy+ 12+1 30. f(x, y) = x2+ 2xy + 102 31. f(x, y) = 6xy - 3y2 - 2x + 4y - 1 32. f(x, y) = 2xy + 12+ 2x -1 33. f (x, y) = - 2x2 + 2xy - 25y2 - 2x + 8y -1 34. f(x, y) = 3x2 + 8xy - 3y2 - 2x+ 4y+ 1 ATTACHMENT PREVIEW Download attachment IMG_0491.jpeg

25) ( 9 5 , 9 1 ) is actually a maximum of f. 29) (0,0) is a... View the full answer
