For the following graph, express the interval shown using interval notation?

The interval notation is;

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;

Repeated

the answer would be c:   ax + b = ax + c
