extreme f(x)=xln(x/6)

Solution

extreme points

f (x) = x ln (\frac{x}{6})

Solution

Minimum (\frac{6}{e}, - \frac{6}{e})

Solution steps

f^{'} (x) = ln (\frac{x}{6}) + 1

Find intervals:

Decreasing

: 0 < x < \frac{6}{e},

Increasing

: \frac{6}{e} < x < \infty

Plug

x = \frac{6}{e}

into

x ln (\frac{x}{6}) : - \frac{6}{e}

Minimum (\frac{6}{e}, - \frac{6}{e})

f (x) = - x^{2} + 3 x^{2} + 9 x + 1

extreme f(x)= t/(t-1)(2.3)extreme points

f (x) = \frac{t}{t - 1} (2.3)

extreme f(x)=(x^2+1)(4x^2-1)extreme points

f (x) = (x^{2} + 1) (4 x^{2} - 1)

72 y^{2} + x^{2} - x^{2} y

extreme f(x)=x^4-32x+3 extreme points

f (x) = x^{4} - 32 x + 3
