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. Example: A = {2,4,6,8,10} write this set in set builder form. Solution: A = {x/x is even and x<12}. or A = {2x/x is a natural number and x£5}.
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.
