I do not understand setbuilder notation.....

Assistance needed.
You might get assistance faster if you actually put the SCHOOL SUBJECT in the School Subject box. Then math tutors would find your posts faster if they're online. 
4 (3y + 13) < 16y  28

Use set builder notation to represent the following set.
{... 3, 2, 1, 0}
