extreme 2x+(27)/(x^2)

Solution

extreme points

2 x + \frac{27}{x ^{2}}

Solution

Minimum (3, 9)

Solution steps

f^{'} (x) = 2 - \frac{54}{x ^{3}}

Find intervals:

Increasing

: - \infty < x < 0,

Decreasing

: 0 < x < 3,

Increasing

: 3 < x < \infty

Plug

x = 3

into

2 x + \frac{27}{x ^{2}} : 9

Minimum (3, 9)

Popular Examples

extreme f(x)=5x^2sqrt(1+x)extreme points

f (x) = 5 x^{2} 1 + x

extreme f(x)=x^3-3/2 x^2-18x extreme points

f (x) = x^{3} - \frac{3}{2} x^{2} - 18 x

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

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

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

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

extreme f(x)=3x^2-4x+5 extreme points

f (x) = 3 x^{2} - 4 x + 5
