$P (x) = - 2 x^{3} - 15 x^{2} + 2 x + 88$

Step 1

Graph the polynomial in order to determine the intervals over which it is increasing or decreasing.

Increasing on: $(- \frac{15 + \sqrt{237}}{6}, - \frac{15 - \sqrt{237}}{6})$

Decreasing on: $(- \infty, - \frac{15 + \sqrt{237}}{6}), (- \frac{15 - \sqrt{237}}{6}, \infty)$
