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

Solution

extreme points

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

Solution

Minimum (0, - 2)

Solution steps

f^{'} (x) = \frac{12 x}{( x ^{2} + 3 ) ^{2}}

Find intervals:

Decreasing

: - \infty < x < 0,

Increasing

: 0 < x < \infty

Plug

x = 0

into

- \frac{6}{x ^{2} + 3} : - 2

Minimum (0, - 2)

Popular Examples

range of sqrt(|x|-1)+3 range

∣ x ∣ - 1 + 3

domain of f(x)=(x-6)^2 domain

f (x) = (x - 6)^{2}

asymptotes of f(x)=sqrt(12-3x)asymptotes

f (x) = 12 - 3 x

intercepts of (2x^2+7x-15)/(3x^2-14x+15)intercepts

\frac{2 x ^{2} + 7 x - 15}{3 x ^{2} - 14 x + 15}

domain of (x-5)/x domain

\frac{x - 5}{x}
