extreme x+(108)/(x^2)

Solution

extreme points

x + \frac{108}{x ^{2}}

Solution

Minimum (6, 9)

Solution steps

f^{'} (x) = 1 - \frac{216}{x ^{3}}

Find intervals:

Increasing

: - \infty < x < 0,

Decreasing

: 0 < x < 6,

Increasing

: 6 < x < \infty

Plug

x = 6

into

x + \frac{108}{x ^{2}} : 9

Minimum (6, 9)

Popular Examples

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

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

extreme f(x)=5x-ln(x)extreme points

f (x) = 5 x - ln (x)

extreme f(x)=x^4-12x^3+16x^2+5 extreme points

f (x) = x^{4} - 12 x^{3} + 16 x^{2} + 5

extreme f(x)=4x^3-2y^2-12x+8y extreme points

f (x) = 4 x^{3} - 2 y^{2} - 12 x + 8 y

extreme f(x)=-x^3+3x-3 extreme points

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