Find the local extrema of the following function. f(x,y) = x³ - 3xy² +12y² For the critical points that do not fail the second-derivative test, determine whether these points are local maxima, lo minima, or saddle points. Select the correct choice below and fill in the answer box to complete your choice. (Type an ordered pair. Use a comma to separate answers as needed.) A. The function has (a) local minimum/minima at (x,y) = . B. The function has (a) local maximum/maxima at (x,y)= C. There is/are (a) saddle point(s) at (x,y)=¯. Does the second-derivative test for local extrema fail at any of the critical points? Select the correct choice below ar necessary, fill in the answer box to complete your choice. (Type an ordered pair. Use a comma to separate answers as needed.) O A. The second-derivative test for local extrema fails at (x,y)= B. The second-derivative test for local extrema does not fail for any of the critical points. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
