The compound inequality that describes the graph is 1 < x < 3.
The graph shows a number line with an empty circle at 1 and a filled circle at 3. This means that 1 is not included in the solution, but 3 is.
The line extends infinitely in both directions to the left of 1 and the right of 3. This means that the inequality includes all numbers less than 1 and all numbers greater than 3.
Therefore, the most accurate compound inequality to describe the graph is 1 < x < 3.
It's important to note that other compound inequalities could also technically describe the graph, such as x < 5 or x > -2. However, these inequalities are less specific than 1 < x < 3 and do not accurately capture the fact that 1 and 3 are not included in the solution.
