So once you solve the inequality you have...
2<x</=3
this means that x is greater than negative 2 but less than or equal to 3.
To graph, you draw a number line, you can just put values ranging from 3 to 4. Now you draw a line segment on the number line which satisfies the conditions that make the inequality true. You would draw a line segment from 2 to 3 because they make the inequality true. However, since the solution set does not contain 2 it has an open circle on top and 3 has a closed circle on top because it is included.
