12

Find all local extreme values of the given function and identify each as a local maximum, local minimum, or saddle point. f(x,y) = x + y-27x -147y -6 O A. f( - 3, - 7) = 734, local maximum B. f( - 3, - 7) =734, local maximum; f(3,7) = - 746, local minimum O c. f(3, - 7) =626, saddle point; f( -3,7) = - 638, saddle point O D. f(3,7) = - 746, local minimum; f(3, - 7) =626, saddle point; f( -3,7) = -638, saddle point, f( - 3, - 7) =734, local maximum
