inflection f(x)=x^3-9x^2

Solution

inflection points

f (x) = x^{3} - 9 x^{2}

Solution

(3, - 54)

Solution steps

f^{''} (x) = 6 x - 18

Find intervals:

Concave Downward

: - \infty < x < 3,

Concave Upward

: 3 < x < \infty

Plug

x = 3

into

x^{3} - 9 x^{2} : - 54

(3, - 54)

Popular Examples

extreme f(x)=x^4-5x^3+5x^2-3 extreme points

f (x) = x^{4} - 5 x^{3} + 5 x^{2} - 3

monotone-0.5x^2-3 monotone intervals

- 0.5 x^{2} - 3

asymptotes of f(x)=3x^6+7x^4+9x asymptotes

f (x) = 3 x^{6} + 7 x^{4} + 9 x

inverse of f(x)=sqrt(x^2+1)inverse

f (x) = x^{2} + 1

intercepts of f(x)=3x^2+5x-12 intercepts

f (x) = 3 x^{2} + 5 x - 12
