2x y+1 1. Consider the following statements about the surface equation z = and In(y)+1 the point P(-2,1) in your domain: I. The directional derivative of z at point P is minimum in the direction of the vector W = (3.2) II. The directional derivative of z at point P is maximum if computed in the direction of the vector w = (2,5). There is no direction from P such that the directional derivative of z computed in that direction yields 5. Which of the above statements are TRUE: A) Only I and III. B) None. C) Only the I. D) Only
