(1 point) Suppose f(x, y) = %, P = (2, 3) and V = 2i 1j. A. Find the gradient of f. Vf = i+ j Note: Your answers should be expressions of x and y; e.g. "3x - 4y" B. Find the gradient of f at the point P. (W) (P) = i+ .i Note: Your answers should be numbers C. Find the directional derivative of f at P in the direction of v. Duf = Note: Your answer should be a number D. Find the maximum rate of change of f at P. Note: Your answer should be a number E. Find the (unit) direction vector in which the maximum rate of change occurs at P. II = H. Note: Your answers should be numbers
