$2\lt x \le 8$ 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. (refer to the attached image in the answer part above)
