Consider a function defined on R² by f(x, y) = y(x + 1)(2 − x − y). (a) Find all four critical points of the function f(x, y). (b) For the critical points not lying in the x-axis, calculate the Hessian matrix for each of them and determine whether the critical point is local maximum/minimum or saddle.
