extreme f(x)=-(x+4)^3

Solution

extreme points

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

Solution

Saddle (- 4, 0)

Solution steps

f^{'} (x) = - 3 x^{2} - 24 x - 48

Find intervals:

Decreasing

: - \infty < x < - 4,

Decreasing

: - 4 < x < \infty

Plug

x = - 4

into

- (x + 4)^{3} : 0

Saddle (- 4, 0)

Popular Examples

extreme f(x,y)=sqrt(4-x^2-4y^2)extreme points

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

extreme (ln(x))/(x^2)extreme points

\frac{ln ( x )}{x ^{2}}

extreme f(t)=e^{-at}extreme points

f (t) = e^{- a t}

extreme f(x,y)=ln(1-x^2-y^2)extreme points

f (x, y) = ln (1 - x^{2} - y^{2})

extreme f(x)=(x-5)^2 extreme points

f (x) = (x - 5)^{2}
