Find a unit vector in the direction in which f(x, y) = 6x7y³ increases most rapidly at P(-1, 1), and find the rate of change of f at P in that direction. NOTE: Enter the exact answers. u = ||Vf(-1, 1) || = 2. Find a unit vector in the direction in which f(x, y) = 3 - 2x² - 2y² decreases most rapidly at P(-3,-1), and find the rate of change of f at P in that direction. NOTE: Enter the exact answers. u = -||Vf(-3,-1)|| = Find a unit vector in the direction in which f(x, y) = 6x7y³ increases most rapidly at P(-1, 1), and find the rate of change of f at P in that direction.
