Answer:
(-2,6]
Step-by-step explanation:
to find the domain, just looks for the x axis
========================================================
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 [tex]-2 < \text{x} \le 6[/tex] 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.
