extreme x+y-xy

Solution

extreme points

x + y - x y

Solution

Saddle (1, 1)

Solution steps

Find the critical points:

(1, 1)

\frac{\partial ^{2} f}{\partial x ^{2}} = 0

D (x, y) = - 1

Check the sign of at each critical point

Check critical point

(1, 1) :

Saddle

Saddle (1, 1)

Popular Examples

extreme p(x)=3x^4+2x^3+5x^2+ax-2 extreme points

p (x) = 3 x^{4} + 2 x^{3} + 5 x^{2} + a x - 2

extreme f(x)=x^2-5x+2 extreme points

f (x) = x^{2} - 5 x + 2

extreme f(x)=(x^2)/9+11+6/x extreme points

f (x) = \frac{x ^{2}}{9} + 11 + \frac{6}{x}

extreme f(x)=-12x-6 extreme points

f (x) = - 12 x - 6

extreme f(x,y)=(x^2-5y^2)e^x extreme points

f (x, y) = (x^{2} - 5 y^{2}) e^{x}
