extreme x-8\sqrt[3]{x}

Solution

extreme points

x - 8 3 x

Solution

Maximum (- \frac{16 2}{3 3}, \frac{32 2}{3 3}), Minimum (\frac{16 2}{3 3}, - \frac{32 2}{3 3})

Solution steps

f^{'} (x) = 1 - \frac{8}{3 x ^{\frac{2}{3}}}

Find intervals:

Increasing

: - \infty < x < - \frac{16 2}{3 3},

Decreasing

: - \frac{16 2}{3 3} < x < 0,

Decreasing

: 0 < x < \frac{16 2}{3 3},

Increasing

: \frac{16 2}{3 3} < x < \infty

Plug

x = - \frac{16 2}{3 3}

into

x - 8 3 x : \frac{32 2}{3 3}

Maximum (- \frac{16 2}{3 3}, \frac{32 2}{3 3})

Plug

x = \frac{16 2}{3 3}

into

x - 8 3 x : - \frac{32 2}{3 3}

Minimum (\frac{16 2}{3 3}, - \frac{32 2}{3 3})

Maximum (- \frac{16 2}{3 3}, \frac{32 2}{3 3}), Minimum (\frac{16 2}{3 3}, - \frac{32 2}{3 3})

f (x) = x^{2} + x y + y^{2} - 22 y + 161

extreme f(x)=x+4/x ,0.2<= x<= 8 extreme points

f (x) = x + \frac{4}{x}, 0.2 \leq x \leq 8

extreme f(x)=(5-x)^{2/3}(1+x)^{1/3}extreme points

f (x) = (5 - x)^{\frac{2}{3}} (1 + x)^{\frac{1}{3}}

extreme x^{1/3}(x^2-9)extreme points

x^{\frac{1}{3}} (x^{2} - 9)

extreme f(x)=x*e^x extreme points

f (x) = x \cdot e^{x}
