Answer:
-6 < x ≤ 6
Step-by-step explanation:
Remember, the domain is the range of the x values.
Also recall that a non-shaded circle represents that that point is not included in the graph. That means it is greater than, not greater than or equal to.
A shaded circle means that that point is included in the graph, meaning that it is less on equal to, not only less than.
If you count the coordinates, you'll see that the non-shaded endpoint is at (-6, -6) and the shaded one is at (6, 6).
To determine the domain, we only need to know the x values.
The x values are -6 and 6, and x is is anywhere between these values: greater than -6, but less than or equal to 6.
Therefore, we produce the inequality -6 < x ≤ 6.
Hope this helps :)
