Let f(x, y) = 1 + xy − 2x + y and let D be the triangular region in double-struck R2 with vertices (−2, 1), (−2, 5), and (2, 1). Find the absolute maximum and minimum values of f on D. Give all points where these extreme values occur. (Order your answers from smallest to largest x, then from smallest to largest y.)
