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 lfthe second derivative test IS inconclusive, so state, f(x,y)=x3 yz 12x+10y Select the cenect choice below and, If necessary' ll in the answer box to cemplete your choice. A- The pomus) where f(x,y) has a possible relative maximum or minimum isfare (Type an ordered pair, Use a comma to separate answers as needed) O B. There is no possible relative maXimum or minimum
