Question

Use set builder notation to give a description of each of these sets.
a) {0, 3, 6, 9, 12}

Answer 1

The set {0, 3, 6, 9, 12} can be described in set builder notation as x .

Step-by-step explanation:

The set in question, {0, 3, 6, 9, 12}, can be described in set builder notation as:

x = 3n and 0 ≤ n < 5

This notation states that the set contains elements 'x' such that 'x' can be generated by multiplying 3 by an integer 'n' where 'n' ranges from 0 to 4.
