(a) Show that a differentiable function of decreases most rapidly at x in the direction opposite the gradient vector, that is, in the direction of -f(x). (Do this on paper. Your instructor may ask you to turn in this work.) (b) Use the result of part(a) to find the direction in which the function f(x, y) = xy - x¹y³ decreases fastest at the point (-1, -1). -f(-1, -1) = <
