extreme f(x)=x^3-9x^2+27x-26

Solution

extreme points

f (x) = x^{3} - 9 x^{2} + 27 x - 26

Solution

Saddle (3, 1)

Solution steps

f^{'} (x) = 3 x^{2} - 18 x + 27

Find intervals:

Increasing

: - \infty < x < 3,

Increasing

: 3 < x < \infty

Plug

x = 3

into

x^{3} - 9 x^{2} + 27 x - 26 : 1

Saddle (3, 1)

Popular Examples

extreme f(x)=(x^2-10x+25)/(x-8)extreme points

f (x) = \frac{x ^{2} - 10 x + 25}{x - 8}

extreme f(x)=(-2)/3 x^3+10x^2-48x-1 extreme points

f (x) = \frac{- 2}{3} x^{3} + 10 x^{2} - 48 x - 1

extreme x^{2/3}(x^3-44)extreme points

x^{\frac{2}{3}} (x^{3} - 44)

extreme 2x^2+16x-4 extreme points

2 x^{2} + 16 x - 4

extreme (x^5)/(20)-3x^3 extreme points

\frac{x ^{5}}{20} - 3 x^{3}
