extreme f(x)=-4x^2y+4xy^2

extreme points

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

None

Solution steps

Find the critical points:

None

- 4 \cdot x^{2} \cdot y + 4 \cdot x \cdot y^{2}

has no critical points, therefore there are no extreme points

None

x^{3} - 3 x^{2} - 5 x - 5

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

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

f (x) = 4 x^{5} + 25 x^{4} - 40 x^{3} - 1

f (x, y) = 6 x y

What is the extreme f(x)=-4*x^2*y+4*x*y^2 ?
The extreme f(x)=-4*x^2*y+4*x*y^2 is None
