What does it mean for a set to be "closed"? (1 point)

Question

The set has a finite number of members, as opposed to being infinitely large.
Members of a closed set cannot be added subtracted, multiplied or divided

An operation performed on members of that set will result in a member of the
same set
An expression belonging to a closed set cannot be used to create an expression
.hat is not of that set

Answer 1

In the context of mathematics, particularly in set theory and algebra, a set is said to be "closed" under an operation if performing that operation on members of the set always produces a member of the same set.

Therefore, the correct interpretation from your options would be:

An operation performed on members of that set will result in a member of the same set.

This means that if you take any two elements from the set and apply the operation (like addition, multiplication, etc.), the result will also be an element of that same set.
