extreme f(x)=(x^2)/2-4x

Solution

extreme points

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

Solution

Minimum (4, - 8)

Solution steps

f^{'} (x) = x - 4

Find intervals:

Decreasing

: - \infty < x < 4,

Increasing

: 4 < x < \infty

Plug

x = 4

into

\frac{x ^{2}}{2} - 4 x : - 8

Minimum (4, - 8)

Popular Examples

extreme f(x)=x^2e^{2x}extreme points

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

extreme y=2x^3+3x^2-12x extreme points

y = 2 x^{3} + 3 x^{2} - 12 x

extreme f(x)=sqrt(y-x)extreme points

f (x) = y - x

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

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

extreme f(x,y)= 1/2 x^4-3xy+3y^4 extreme points

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