extreme f(x)=3x^3+8

Solution

extreme points

f (x) = 3 x^{3} + 8

Solution

Saddle (0, 8)

Solution steps

f^{'} (x) = 9 x^{2}

Find intervals:

Increasing

: - \infty < x < 0,

Increasing

: 0 < x < \infty

Plug

x = 0

into

3 x^{3} + 8 : 8

Saddle (0, 8)

Popular Examples

shift f(x)=2sin(pix+4)-2 shift

f (x) = 2 sin (π x + 4) - 2

slope ofintercept 4x+3y=24 slope intercept

4 x + 3 y = 24

shift f(x)=cos(2(x-pi/2))shift

f (x) = cos (2 (x - \frac{π}{2}))

inverse of f(x)=sin(5x+2)inverse

f (x) = sin (5 x + 2)

domain of x/(x-6)domain

\frac{x}{x - 6}
