extreme f(x)=2x^3-5

Solution

extreme points

f (x) = 2 x^{3} - 5

Solution

Saddle (0, - 5)

Solution steps

f^{'} (x) = 6 x^{2}

Find intervals:

Increasing

: - \infty < x < 0,

Increasing

: 0 < x < \infty

Plug

x = 0

into

2 x^{3} - 5 : - 5

Saddle (0, - 5)

Popular Examples

extreme f(x)=68x-x^2 extreme points

f (x) = 68 x - x^{2}

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

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

extreme f(y,x)=ye^{x^2-y^2}extreme points

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

extreme f(x,y)=(2x^2-3y^2)/(y^2+1)extreme points

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

extreme x^3+x,-1<= x<= 2 extreme points

x^{3} + x, - 1 \leq x \leq 2
