monotone f(x)=x^3+3x^2-4

monotone intervals

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

Increasing : - \infty < x < - 2, Decreasing : - 2 < x < 0, Increasing : 0 < x < \infty

Solution steps

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

Find intervals:

Increasing

: - \infty < x < - 2,

Decreasing

: - 2 < x < 0,

Increasing

: 0 < x < \infty

Increasing : - \infty < x < - 2, Decreasing : - 2 < x < 0, Increasing : 0 < x < \infty

\frac{x}{1 - x}

\frac{- 1 + 3 8 x + 1}{4}

3 tan (2 x + \frac{π}{5})

f (x) = - 1 - x

f (x) = 2 x - 5 x^{2}
