extreme f(x)=-4x^3

Solution

extreme points

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

Solution

Saddle (0, 0)

Solution steps

f^{'} (x) = - 12 x^{2}

Find intervals:

Decreasing

: - \infty < x < 0,

Decreasing

: 0 < x < \infty

Plug

x = 0

into

- 4 x^{3} : 0

Saddle (0, 0)

Popular Examples

inverse of f(x)=5-7x inverse

f (x) = 5 - 7 x

perpendicular 5x+3y=15 perpendicular

5 x + 3 y = 15

y = 3^{x}

slope ofintercept 2(3-x)=6y+1 slope intercept

2 (3 - x) = 6 y + 1

inverse of \sqrt[3]{x^2}inverse
