monotone f(x)= 2/(x+5)

monotone intervals

f (x) = \frac{2}{x + 5}

Decreasing : - \infty < x < - 5, Decreasing : - 5 < x < \infty

Solution steps

f^{'} (x) = - \frac{2}{( x + 5 ) ^{2}}

Find intervals:

Decreasing

: - \infty < x < - 5,

Decreasing

: - 5 < x < \infty

Decreasing : - \infty < x < - 5, Decreasing : - 5 < x < \infty

(2.4) (4.4)

\frac{x ^{3}}{x ^{3} + 1}

e^{- x} - 2

\frac{- 12 x - 40}{9 x + 6}

(- 44, - 21), (43, - 32)
