monotone f(x)=x^4

monotone intervals

f (x) = x^{4}

Decreasing : - \infty < x < 0, Increasing : 0 < x < \infty

Solution steps

f^{'} (x) = 4 x^{3}

Find intervals:

Decreasing

: - \infty < x < 0,

Increasing

: 0 < x < \infty

Decreasing : - \infty < x < 0, Increasing : 0 < x < \infty

x e^{x}

\frac{4}{( x + 1 ) ^{2}}

f (x) = 3 - 2 x + 8

f (x) = x^{4} - 32 x^{2} + 9

f (x) = sin (\frac{2 π}{3}) x
