extreme f(x,y)=16x+12y-2x^2-3y^2

extreme points

f (x, y) = 16 x + 12 y - 2 x^{2} - 3 y^{2}

Maximum (4, 2)

Solution steps

Find the critical points:

(4, 2)

\frac{\partial ^{2} f}{\partial x ^{2}} = - 6

D (x, y) = 24

Check the sign of at each critical point

Check critical point

(4, 2) :

Maximum
