$f (x) = 5 x^{4} - 29 x^{3} + 20 x^{2}$

Step 1

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

Increasing on: $(0, \frac{87 - \sqrt{4369}}{40}), (\frac{87 + \sqrt{4369}}{40}, \infty)$

Decreasing on: $(- \infty, 0), (\frac{87 - \sqrt{4369}}{40}, \frac{87 + \sqrt{4369}}{40})$
