extreme f(x)=2xln(x)

Solution

extreme points

f (x) = 2 x ln (x)

Solution

Minimum (\frac{1}{e}, - \frac{2}{e})

Solution steps

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

Find intervals:

Decreasing

: 0 < x < \frac{1}{e},

Increasing

: \frac{1}{e} < x < \infty

Plug

x = \frac{1}{e}

into

2 x ln (x) : - \frac{2}{e}

Minimum (\frac{1}{e}, - \frac{2}{e})

Popular Examples

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

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

extreme f(x)=x^2e^{-2x}extreme points

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

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

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

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

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

extreme f(x)=-x^3+3x^2+45x-42 extreme points

f (x) = - x^{3} + 3 x^{2} + 45 x - 42
