inflection-x^3+9x^2-27x+8

Solution

inflection points

- x^{3} + 9 x^{2} - 27 x + 8

Solution

(3, - 19)

Solution steps

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

Find intervals:

Concave Upward

: - \infty < x < 3,

Concave Downward

: 3 < x < \infty

Plug

x = 3

into

- x^{3} + 9 x^{2} - 27 x + 8 : - 19

(3, - 19)

Popular Examples

(5, 9), (10, - 1)

extreme f(x)=x^6-3x^5 extreme points

f (x) = x^{6} - 3 x^{5}

extreme f(x)=x^2-3x+1 extreme points

f (x) = x^{2} - 3 x + 1

midpoint (5,5),(-10,-2)midpoint

(5, 5), (- 10, - 2)

range of f(x)=sqrt(1-x^2)range

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