1. Consider the following statements about the surface equation z = ye-* - 2xy and the point P(0, -2) in your domain: I. If we calculate the directional derivative of z in the direction of any vector @ e R-, it is certain that Do z (P) = v37. II. There is no direction from P such that the directional derivative of z computed in that direction yields 1. III. The value of the directional derivative of z at point P calculated in the direction of the vector u = (3, 4) is equal to -14. Which of the above statements are TRUE: A) Only I and III. B) None. C) Only the I. D) Only
