Q.56 Define f: R2 R by fx)= x +2y-x for (Cxy) E R Let D (.y)eRi+y' s 1) and E = {o)ER+Gs i Consider the sets Dmax {(a, b) E D : f has absolute maximum on D at (a, b)}. Dmin((a, b) E D:f has absolute minimum on D at (a, b). Emax((c, d) E E : fhas absolute maximum on E at (c, d). Emin((c, d) E E : fhas absolute minimum on E at (c, d)}. Then the total number of elements in the set Dmax U Dmin U Emax U Emin is equal to
