extreme x-3x^{1/3}

Solution

extreme points

x - 3 x^{\frac{1}{3}}

Solution

Minimum (- 1, 2), Maximum (1, - 2)

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < - 1,

Increasing

: - 1 < x < 1,

Decreasing

: 1 < x < \infty

Plug

x = - 1

into

x - 3 x^{\frac{1}{3}} : 2

Minimum (- 1, 2)

Plug

x = 1

into

x - 3 x^{\frac{1}{3}} : - 2

Maximum (1, - 2)

Minimum (- 1, 2), Maximum (1, - 2)

Popular Examples

extreme f(x,y)=e^y(y^2-x^2)extreme points

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

extreme y=x^3 extreme points

y = x^{3}

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

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

extreme (2x^2)/(x^2-25)extreme points

\frac{2 x ^{2}}{x ^{2} - 25}

extreme f(x)= x/(x^2+81)extreme points

f (x) = \frac{x}{x ^{2} + 81}
