The Figure above shows the graph of $$f(x) = \frac{x^5}{5} - \frac{x^4}{2} -\frac{x^3}{3}+x^2.$$ The answers below are all integers.
The graph of $f$ shows relative maxima and relative minima,
for a total of relative extrema.

The graph is increasing on the bounded interval $[$ , $]$.
Note: a bounded interval is one of finite length.
