The interval notation is;
[tex](-\infty,4][/tex]
Step-by-step explanation:
The solution set of the inequality represented on the number line is

The boundary 4 is inclusive in the solution set, so we use square bracket "[ ]" to show inclusion and open bracket "()" to show that, that part of the interval in not bounded.
In interval notation, we can write this as;
[tex](-\infty,4][/tex]
