Which of the following is a closed interval?
Answer and explanation
Correct answer: [1, 6]
A closed interval contains both of its endpoints. This is shown by square brackets at both ends. In [1, 6], both 1 and 6 are included, and every real number between them is also included. The other choices exclude at least one endpoint because they contain a round bracket. Therefore, [1, 6] is the only closed interval.
