Answer:
Step-by-step explanation:
When the end points are shaded in as they are in this question, the ≤ or ≥ set of symbols should be used. Since both ends are shaded in, the answer cannot include something that indicates that the end points are not included.
That makes A C and D all incorrect because at least one of the end points is indicated to be open in your choice. Neither one is open.
The answer is B.
