extreme f(x)= 1/(x^2-1)

Solution

extreme points

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

Solution

Maximum (0, - 1)

Solution steps

f^{'} (x) = - \frac{2 x}{( x ^{2} - 1 ) ^{2}}

Find intervals:

Increasing

: - \infty < x < - 1,

Increasing

: - 1 < x < 0,

Decreasing

: 0 < x < 1,

Decreasing

: 1 < x < \infty

Plug

x = 0

into

\frac{1}{x ^{2} - 1} : - 1

Maximum (0, - 1)

Popular Examples

extreme f(x)=-((x-5))/(e^x)extreme points

f (x) = - \frac{( x - 5 )}{e ^{x}}

inverse of y=x inverse

y = x

domain of f(x)=(x^2+x)/x domain

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

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

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

parity f(x)=x^6+x parity

f (x) = x^{6} + x
