extreme (-4)/(x^2-9)

Solution

extreme points

\frac{- 4}{x ^{2} - 9}

Solution

Minimum (0, \frac{4}{9})

Solution steps

f^{'} (x) = \frac{8 x}{( x ^{2} - 9 ) ^{2}}

Find intervals:

Decreasing

: - \infty < x < - 3,

Decreasing

: - 3 < x < 0,

Increasing

: 0 < x < 3,

Increasing

: 3 < x < \infty

Plug

x = 0

into

\frac{- 4}{x ^{2} - 9} : \frac{4}{9}

Minimum (0, \frac{4}{9})

Popular Examples

extreme f(x)=e^{x^2-2x-1}extreme points

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

extreme f(x)=137 extreme points

f (x) = 137

extreme f(x)=|x|-3|x+1|extreme points

f (x) = ∣ x ∣ - 3 ∣ x + 1 ∣

extreme f(x)=2cos(x)+cos^2(x)extreme points

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

extreme f(x)=-x^3-4.5x^2-6x+2 extreme points

f (x) = - x^{3} - 4.5 x^{2} - 6 x + 2
