Answer:
[tex](-\infty,-6) \cup (-6,4) \cup (4,\infty)[/tex]
Step-by-step explanation:
The graph given is unbounded at the values of [tex]x[/tex]: [tex]-6[/tex] and [tex]4[/tex]. So, we should not include them.
Domain: [tex]x \in \{ \space \mathbb{R} \space | \space (-\infty,-6) \cup (-6,4) \cup (4,\infty)\}[/tex]
