extreme P(x,y)=12x^6-7x^3y-10y^2

extreme points

P (x, y) = 12 x^{6} - 7 x^{3} y - 10 y^{2}

None

Solution steps

Find the critical points:

None

12 x^{6} - 7 x^{3} y - 10 y^{2}

has no critical points, therefore there are no extreme points

None

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

f (x, y) = x^{3} - 6 x y + 8 y^{3}

f (x, y) = x^{2} + x^{2} y + y^{2} + 1

f (x) = 2 x + cos (x)

f (x) = (x^{2} + 1)^{3}
