Question: The function f(x, y) = a3 +10x2- 2x y + y2 + 24 x + 16 has two critical points. One is a saddle point

The function f(x, y) = a3 +10x2- 2x y + y2

The function f(x, y) = a3 +10x2- 2x y + y2 + 24 x + 16 has two critical points. One is a saddle point with x-coordinate -4 and value of D = -6 1209 : -6 The other is a Local Minimum. with x-coordinate -2 and value of D = 18 Here D = fax fyy - fay
