monotone f(x)=(4^x)/(1+4^x)

monotone intervals

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

Increasing : - \infty < x < \infty

Solution steps

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

Find intervals:

Increasing

: - \infty < x < \infty

Increasing : - \infty < x < \infty

f (x) = x^{3} - x^{2} - x + 9

(1, 5), (7, 13)

f (x) = (x^{2} - 6 x)^{\frac{1}{4}}

\frac{x ^{3} - x ^{2} - 2 x}{- 3 x ^{2} + 27}
