Question

How to change sets in set builder form easily without any confusion? ​

Answer 1

Answer:

For example, C={2,4,5} denotes a set of three numbers: 2, 4, and 5, and D={(2,4),(−1,5)} denotes a set of two pairs of numbers. ... Another option is to use set-builder notation: F={n3:n is an integer with 1≤n≤100} is the set of cubes of the first 100 positive integers.

Answer 2

Answer:

We can write a finite set in Roster form easily. But when there are infinite number of elements, it is difficult to write all of them in the Roster form.

For example, the set of Integers, Natural Numbers, or Rational Numbers can be described easily in set builder form but not in a Roster form.
