$\left\{x | 1 \lt x \le 6\right\}$ Refer to the attached image below for the graph.
An bracket on the left means that 1 is not included in the set. A parenthesis on the right means that 6 is included in the set. Therefore. the set-builder form of the given interval is: $\left\{x | 1 \lt x \le 6\right\}$ To graph the interval, plot a hole (or hollow dot) at x=1 and a solid dot at x=6, then shade the region between them. (refer to the attached image in the answer part for the graph)
