1. For f(x, y, z) = xy + yz + xz, determine the directional derivative at (1,-1, 2) in the direction of (3, 6, -2). At that point, what are the directions of the largest ascent and largest descent? What are the directional derivatives in those directions? Does your first answer in this question lie between the two values?
