4.27 Set Builder Form

Set builder form:
This method is also known as Property method. In this method, a set is represented by stating all the properties which are satisfied by the elements of the set and not by any other element. If A contains all values of 'x' for which the condition P(x) is true, then we write A = {x: P(x)}.
While writing in the Roster form we write an element only once even though it is repeated any number of times.
A = {2,4,6,8,10} write this set in set builder form.
A = {x/x is even and x<12}.
A = {2x/x is a natural number and x5}.

Note: There may be more than one way to represent a set in set builder form.

Directions: Write the given sets in set builder form. Also write at least ten examples of your own.
Q 1: Q = {0,1,2,3,4,5,6}, write this in set builder form.
Q = {x/x is a whole number and x = 7}
