A function is defined on R2 as f(x,y) = 2x3 – 6xy + 2xy2 +2. Find any critical / stationary points for the function f. Determine if these points are local minimum, local maximum or hall point. b) Find the gradient of the function f in the point (1,1). Find the directional derivative of f at the point (1,1) in the direction of the vector [-1, -1].
