extreme f(x)= 4/(x^2+1)

Solution

extreme points

f (x) = \frac{4}{x ^{2} + 1}

Solution

Maximum (0, 4)

Solution steps

f^{'} (x) = - \frac{8 x}{( x ^{2} + 1 ) ^{2}}

Find intervals:

Increasing

: - \infty < x < 0,

Decreasing

: 0 < x < \infty

Plug

x = 0

into

\frac{4}{x ^{2} + 1} : 4

Maximum (0, 4)
