extreme f(x)=-x^3-1

Solution

extreme points

f (x) = - x^{3} - 1

Solution

Saddle (0, - 1)

Solution steps

f^{'} (x) = - 3 x^{2}

Find intervals:

Decreasing

: - \infty < x < 0,

Decreasing

: 0 < x < \infty

Plug

x = 0

into

- x^{3} - 1 : - 1

Saddle (0, - 1)

Popular Examples

extreme f(x,y)=4xy-x^3-2y^2 extreme points

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

extreme L(x,y)=4+x^3+y^3-3xy extreme points

L (x, y) = 4 + x^{3} + y^{3} - 3 x y

extreme f(x,y)=x^3+3y^3+3x^2+3y^2+24 extreme points

f (x, y) = x^{3} + 3 y^{3} + 3 x^{2} + 3 y^{2} + 24

extreme f(x)=2x+2/x extreme points

f (x) = 2 x + \frac{2}{x}

extreme f(x)=((x^2-4))/(x^2+4)extreme points

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