extreme f(x)=5xln(x)

Solution

extreme points

f (x) = 5 x ln (x)

Solution

Minimum (\frac{1}{e}, - \frac{5}{e})

Solution steps

f^{'} (x) = 5 (ln (x) + 1)

Find intervals:

Decreasing

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

Increasing

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

Plug

x = \frac{1}{e}

into

5 x ln (x) : - \frac{5}{e}

Minimum (\frac{1}{e}, - \frac{5}{e})

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

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

extreme f(x,y)=9e^{4y-x^2-y^2}extreme points

f (x, y) = 9 e^{4 y - x^{2} - y^{2}}

extreme f(x)=x-rx(1-x)extreme points

f (x) = x - r x (1 - x)

extreme f(x,y)=x^3+y^3+3x^2-6y^2-5 extreme points

f (x, y) = x^{3} + y^{3} + 3 x^{2} - 6 y^{2} - 5

extreme f(x)=0.01x^3-0.45x^2+2.43x+300 extreme points

f (x) = 0.01 x^{3} - 0.45 x^{2} + 2.43 x + 300
