Find all points (icy) where f()(,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)=x3 yz 12x+10y Select the correct choice below and, if necessary fill in the answer box to complete your choice. 'vA- The pornt(s} where f(x,y) has a possible relative maximum or minimum isfare {2,5},(2,5} . (Type an ordered pair. Use a comma to separate answers as needed.) 3. There is no possible relative maximum or minimum. Select the correct choice below and, if necessary, ll in the answer box to complete your choice.
