1. **Problem Statement:** We are given a polynomial function $f(x)$ graphed with specific characteristics and asked to identify which statement is NOT true about $f(x)$.
2. **Given Statements:**
- The range of $f(x)$ is $(-\infty, \infty)$.
- $(x + 6)$ is a factor of $f(x)$.
- $x = 3$ is a triple root of the function.
- As $x \to +\infty$, $f(x) \to -\infty$.
3. **Analyzing the Graph:**
- The graph crosses the x-axis near $-6$, so $(x + 6)$ is likely a factor.
- The graph crosses the x-axis near $1$ and $6$, and has a local maximum between $3$ and $4$.
- The graph starts high at $x = -7$ and ends low at $x = 7$, indicating the leading term has negative leading coefficient and odd degree.
4. **Check the range:**
- The graph goes from about $50$ down to about $-60$, and since it is a polynomial of odd degree, it extends to $\pm \infty$ in $y$ as $x \to \pm \infty$.
- So the range is indeed $(-\infty, \infty)$.
5. **Check $(x + 6)$ factor:**
- Since the graph crosses the x-axis near $-6$, $(x + 6)$ is a factor.
6. **Check if $x=3$ is a triple root:**
- The graph does not cross or touch the x-axis at $x=3$; it has a local maximum between $3$ and $4$ but does not cross the axis there.
- Therefore, $x=3$ is NOT a root, let alone a triple root.
7. **Check end behavior:**
- As $x \to +\infty$, $f(x) \to -\infty$ matches the graph going down on the right.
**Conclusion:** The statement "$x=3$ is a triple root of the function" is NOT a characteristic of $f(x)$.
**Final answer:** $x=3$ is NOT a triple root of $f(x)$.
