extreme 2/(1+x^2)

Solution

extreme points

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

Solution

Maximum (0, 2)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < 0,

Decreasing

: 0 < x < \infty

Plug

x = 0

into

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

Maximum (0, 2)

Popular Examples

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

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

extreme f(x)=xy-2x-y extreme points

f (x) = x y - 2 x - y

extreme f(x)=t^4-2t^2+2 extreme points

f (x) = t^{4} - 2 t^{2} + 2

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

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

extreme y=(x-1)^2(x+1)extreme points

y = (x - 1)^{2} (x + 1)
