Answer: (-4, 2]
============================================================
Explanation:
The graph is a bit small, faded and blurry. However, it appears that there's an open hole when x = -4 and a closed endpoint at x = 2.
If those assumptions are correct, then the domain as a compound inequality is [tex]-4 < x \le 2[/tex] which converts to the interval notation (-4, 2]
We use an open parenthesis to denote an open hole to exclude the endpoint. In contrast, a square bracket denotes a closed endpoint to include the endpoint.
Using words, the domain is the set of real numbers from -4 to 2, excluding -4 but including 2.
