Recall how to graph an inequality on a number line

https://www.shmoop.com/basic-algebra/graphing-inequalities-help.html

The open circle located on 4 means that x cannot be equal to 4. The arrow pointing to the left means that x can be any number less than 4.

Since x can be any number less than 4, the inequality is x<4.
