1. **Problem Statement:** We are given a function $f(x)$ defined on the interval $[-9,9]$ with specific points on its graph. We need to find the $x$-value(s) where the global maximum of $f(x)$ occurs.
2. **Understanding Global Maximum:** The global maximum of a function on a closed interval is the highest value the function attains anywhere on that interval.
3. **Given Points:** The function passes through these points:
- $(-9, -4)$
- $(-7, 5)$
- $(-4, 1)$
- $(-1, -8)$
- $(3, -1)$
- $(7, -4)$
4. **Finding the Maximum Value:** We compare the $y$-values of these points to find the highest one:
- $-4, 5, 1, -8, -1, -4$
5. **Maximum $y$-value:** The highest $y$-value is $5$ at $x = -7$.
6. **Conclusion:** The global maximum value of $f(x)$ is $5$, and it occurs at $x = -7$.
**Final answer:**
$$x = -7$$
