Answer 1

$(x,y) = y2 * . The directional derivative is maximum in the direction of of and the maximum yalue is ll ofll. vf(x,y) = {fe,fy) =<- y² 24 24) 22 R :. vf (1,2) <-4, 4) Hence maximum directional derivative of f(x,y) on the point (1,2) = V-4)2+(4)2 - V16+16 V 32 = 412 Option with answer 412 answer 412 is correct
