========================================================

Step-by-step explanation:

The domain spans from -2 to 6 on the x axis number line.

We exclude -2 because of the open hole; but we include 6 because of the closed circle endpoint.

We could say the domain is
$-2 < \text{x} \le 6$ but it's more compact to write it as (-2,6] which is in interval notation.

Use a curved parenthesis to exclude the endpoint. A square bracket includes the endpoint.
