Answer
$2\lt x \le 8$
Refer to the image below for the graph.
Work Step by Step
A parenthesis on the left means 2 is not included in the set.
A bracket on the right means 8 is included in the set.
Thus, the equivalent inequality of the given interval is:
$2 \lt x \le 8$
To graph the interval on a number line, plot a hole (or hollow dot) at $2$ and plot a solid dot at $8$.
Then shade the region between them.
