Set A is the set of all integers. What type of set is A?
Answer and explanation
Correct answer: Infinite set
The integers are ..., −3, −2, −1, 0, 1, 2, 3, ... . They extend without end in the negative direction and also without end in the positive direction. Consequently, there is no final integer and the set cannot be listed completely. Therefore, the set of all integers is infinite.
