extreme f(x)=6x-7x^{6/7}

Solution

extreme points

f (x) = 6 x - 7 x^{\frac{6}{7}}

Solution

Maximum (1, - 1)

Solution steps

f^{'} (x) = 6 - \frac{6}{x ^{\frac{1}{7}}}

Find intervals:

Increasing

: - \infty < x < 1,

Decreasing

: 1 < x < \infty

Plug

x = 1

into

6 x - 7 x^{\frac{6}{7}} : - 1

Maximum (1, - 1)

Popular Examples

extreme-x^3 extreme points

- x^{3}

extreme f(x)=x(ln(x))^2 extreme points

f (x) = x (ln (x))^{2}

extreme f(x)=x^3+3x^2+4 extreme points

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

extreme f(x)=(x/(\sqrt[3]{x^2-1)})extreme points

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

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