extreme y= x/(x^2+64)

extreme

Minimum (- 8, - \frac{1}{16}), Maximum (8, \frac{1}{16})

Solution steps

f^{'} (x) = \frac{- x ^{2} + 64}{( x ^{2} + 64 ) ^{2}}

Find intervals:

Decreasing

: - \infty < x < - 8,

Increasing

: - 8 < x < 8,

Decreasing

: 8 < x < \infty

Plug

x = - 8

into

\frac{x}{x ^{2} + 64} : - \frac{1}{16}

Minimum (- 8, - \frac{1}{16})

Plug

x = 8

into

\frac{x}{x ^{2} + 64} : \frac{1}{16}

Maximum (8, \frac{1}{16})

Minimum (- 8, - \frac{1}{16}), Maximum (8, \frac{1}{16})

What is the extreme y= x/(x^2+64) ?
The extreme y= x/(x^2+64) is Minimum(-8,-1/16),Maximum(8, 1/16)
