Consider the function

f(x,y) := (0.782x2 - 2y2 + 4.621x3) / (x2 + y2 + 1)


and the corresponding surface z = f(x,y) .


  1. Please find and classify all critical points of f. Give each critical point as a point in 3-space (R3).
  2. Please find the absolute extrema of f on the triangular region bounded by x = -1, y = -1, and y = 1 - x. Find the location of each absolute extremum and the corresponding function values.
