extreme f(x)=x^3-2x^3

Solution

extreme points

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

Solution

Saddle (0, 0)

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 0,

Decreasing

: 0 < x < \infty

Plug

x = 0

into

x^{3} - 2 x^{3} : 0

Saddle (0, 0)

Popular Examples

extreme 5(2e^{-x}x-e^{-x}x^2)extreme points

5 (2 e^{- x} x - e^{- x} x^{2})

extreme y=4x^3-12x extreme points

y = 4 x^{3} - 12 x

extreme f(x)=(x-1)(x^2-2x-2)extreme points

f (x) = (x - 1) (x^{2} - 2 x - 2)

extreme f(x,y)=sqrt(400-9x^2-25y^2)extreme points

f (x, y) = 400 - 9 x^{2} - 25 y^{2}

extreme f(x)=(e^x)/(x^5),x>0 extreme points

f (x) = \frac{e ^{x}}{x ^{5}}, x > 0
