QUESTION 3 Let f be a function of x and y, and suppose that f(1,0) = 5. Suppose that v/(1,0) = (-3,4) Consider the following statements about vf(1,0). O|V/(1,0)| is the size of the biggest directional derivative of f at the point (1,0)- (i) The vector V/(1,0) is orthogonal to the curve f(x.y) =5 (H) At (1,0), f changes most rapidly in the direction of the unit vector (1,0) Which of the above statements is correct? O a. (i) and (ii) are correct. Ob.(1) and (ii) are correct. O.() and (i) are correct. Od. (). (i), and (i) are all correct.
