monotone x^3-x^2-4x

Solution

monotone intervals

x^{3} - x^{2} - 4 x

Solution

Increasing : - \infty < x < \frac{- 13 + 1}{3}, Decreasing : \frac{- 13 + 1}{3} < x < \frac{13 + 1}{3}, Increasing : \frac{13 + 1}{3} < x < \infty

Solution steps

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

Find intervals:

Increasing

: - \infty < x < \frac{- 13 + 1}{3},
