1. **Problem Statement:** Analyze the polynomial function's graph and verify which statements about its characteristics are true.
2. **Key Observations from the Graph:**
- The graph crosses the x-axis near $x=-2$ and $x=2$.
- There are exactly two local extrema: a local maximum near $x=-1$ and a local minimum near $x=1$.
- As $x \to -\infty$, $f(x) \to \infty$.
- As $x \to \infty$, $f(x) \to -\infty$.
- The function crosses the x-axis at $x=2$ with an odd multiplicity (since it crosses rather than just touches).
- The leading coefficient is negative (due to end behavior: left end up, right end down).
- The least possible degree is 5, consistent with the number of extrema and end behavior.
- The range is all real numbers $(-\infty, \infty)$ because the graph extends infinitely in both vertical directions.
3. **Explanation of Statements:**
- The 5th finite differences being constant negative corresponds to a degree 5 polynomial with negative leading coefficient.
- The function is not even (no line symmetry about the y-axis).
- The y-intercept is not negative (graph does not show negative y-intercept).
- The graph does not have an absolute maximum since it goes to infinity as $x \to -\infty$.
4. **Summary of True Statements:**
- As $x \to -\infty$, $f(x) \to \infty$.
- The function has exactly two local extrema.
- The range is $(-\infty, \infty)$.
- The multiplicity of the x-intercept at $x=2$ is odd.
- The least possible degree is 5.
- The leading coefficient is negative.
5. **Final Answer:** The true statements are those marked with [x] in the problem.
