Let f (x, y) = 2x2 + 3y2 represent the height of a mountain above the point (x, y). Let the positive x-direction point East and the positive y-direction point North. Suppose that I am standing above the point P (3, 2) and sit a ball down. Which direction best represents the direction that the ball will start to roll?
