Given the functions f(x,y) = x3 + y3- 3x - 3y

First find the coordinates of all the critical points of f(x,y) and then apply the Second Order Partial Derivative Test to locate all relative maxima, relative minima and saddle points of f(x,y). Justify your answers and show your conclusions using an appropriate table.

[Hint: The domain of f(x,y) is an open region ]
