$\"\"$

Observe the graph, one terminal of the line graph containing circle at $\"\"$ and other terminal of the line graph containing dot at $\"\"$ and the solutions are between $\"\"$ .

So, $\"\"$ is not include in the solution set and $\"\"$ is include in the solution set.

The graph shows the solution $\"\"$ and the inequality is $\"\"$ . $\"\"$

The inequality is $\"\"$ .
