Answer

Refer to the attached image for the graph. The interval notation equivalent of the given set is $(0.5, 3]$.

Work Step by Step

The given set covers the x-values that are greater than 0.5 but not more than 3.. This means that its graph will be the region between 0.5 and 3, where 0,5 is not included while 3 is included. To graph the set, plot a hollow dot (or a hole) at x=0.5 and a solid dot at $x=3$. Then, shade the region between the two numbers. (refer to the attache image below for the graph) The interval notation equivalent of the given set is $(0.5,3]$.
