extreme f(x)= x/(x^2+16)

extreme points

f (x) = \frac{x}{x ^{2} + 16}

Minimum (- 4, - \frac{1}{8}), Maximum (4, \frac{1}{8})

Solution steps

f^{'} (x) = \frac{- x ^{2} + 16}{( x ^{2} + 16 ) ^{2}}

Find intervals:

Decreasing

: - \infty < x < - 4,

Increasing

: - 4 < x < 4,

Decreasing

: 4 < x < \infty

Plug

x = - 4

into

\frac{x}{x ^{2} + 16} : - \frac{1}{8}

Minimum (- 4, - \frac{1}{8})

Plug

x = 4

into

\frac{x}{x ^{2} + 16} : \frac{1}{8}

Maximum (4, \frac{1}{8})

Minimum (- 4, - \frac{1}{8}), Maximum (4, \frac{1}{8})

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

f (x) = 2 x^{3} - 6 x + 4

f (x, y) = x^{2} y + y^{3} - 75 y

f (x, y) = e^{- x - y}

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