First, the graph is overall decreasing with two local maximums and two local minimums.
Second, it has 5 zeros, since there is one intersection and two touching points with the x-axis.
Considering the above observations we can state that:
- The degree of f(x) is odd;
- The leading coefficient is negative;
- There are 5 distinct zeros;
- There are 2 relative maximum values.
