extreme f(x)=2x+8/(x^2)

Solution

extreme points

f (x) = 2 x + \frac{8}{x ^{2}}

Solution

Minimum (2, 6)

Solution steps

f^{'} (x) = 2 - \frac{16}{x ^{3}}

Find intervals:

Increasing

: - \infty < x < 0,

Decreasing

: 0 < x < 2,

Increasing

: 2 < x < \infty

Plug

x = 2

into

2 x + \frac{8}{x ^{2}} : 6

Minimum (2, 6)

Popular Examples

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

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

extreme f(x)=6x^{4/3}-3x^{1/3}extreme points

f (x) = 6 x^{\frac{4}{3}} - 3 x^{\frac{1}{3}}

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

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

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

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

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

f (x, y) = 4 - 2 x - 3 y
