extreme f(x)=(x^4)/4-8x

Solution

extreme points

f (x) = \frac{x ^{4}}{4} - 8 x

Solution

Minimum (2, - 12)

Solution steps

f^{'} (x) = x^{3} - 8

Find intervals:

Decreasing

: - \infty < x < 2,

Increasing

: 2 < x < \infty

Plug

x = 2

into

\frac{x ^{4}}{4} - 8 x : - 12

Minimum (2, - 12)

Popular Examples

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

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

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

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

extreme f(x)=4x^3-16x extreme points

f (x) = 4 x^{3} - 16 x

extreme f(x)=x^{3/4}-2x^{1/4}extreme points

f (x) = x^{\frac{3}{4}} - 2 x^{\frac{1}{4}}

extreme f(t)=t^2-t^2h(t-2)+3h(t-2)extreme points

f (t) = t^{2} - t^{2} h (t - 2) + 3 h (t - 2)
