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

Solution

extreme points

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

Solution

Saddle (0, 4)

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 0,

Decreasing

: 0 < x < \infty

Plug

x = 0

into

- x^{3} + 4 : 4

Saddle (0, 4)

Popular Examples

domain of-sqrt(x)-2 domain

- x - 2

domain of f(x)=3x-2 domain

f (x) = 3 x - 2

domain of-4/x domain

- \frac{4}{x}

inverse of f(x)=(350)/(100+7x^3)inverse

f (x) = \frac{350}{100 + 7 x ^{3}}
