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

Solution

extreme points

\frac{2 ( x + 2 ) ^{2}}{x ^{2}}

Solution

Minimum (- 2, 0)

Solution steps

f^{'} (x) = - \frac{8 ( x + 2 )}{x ^{3}}

Find intervals:

Decreasing

: - \infty < x < - 2,

Increasing

: - 2 < x < 0,

Decreasing

: 0 < x < \infty

Plug

x = - 2

into

\frac{2 ( x + 2 ) ^{2}}{x ^{2}} : 0

Minimum (- 2, 0)

extreme (2x-5)/(x^2-4)extreme points

\frac{2 x - 5}{x ^{2} - 4}

extreme f(x,y)=x^2y+3xy^2 extreme points

f (x, y) = x^{2} y + 3 x y^{2}

extreme f(x)=x^4+y^4-4xy+1 extreme points

f (x) = x^{4} + y^{4} - 4 x y + 1
