extreme f(x,y)=x-2yg(x,y)=x^2+y^2=25

extreme points

f (x, y) = x - 2 y g (x, y) = x^{2} + y^{2} = 25

None

Solution steps

Find the critical points:

None

25

has no critical points, therefore there are no extreme points

None

f (x) = x^{3} + x^{2} y - y^{2} - 4 y

y = x^{\frac{4}{5}} (x - 1)

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

\frac{64}{x ^{2} + 6 x - 7}

f (x) = 6 x e^{- x^{2}}
