WORKBOOK

NOTE: Reading a set written as in set builder form given below.

A = {x : 2 < x < 20 , x N }
Set A
x is a natural number

such that x is greater than 2
x an element of A and less than 20

Example 4: Rewrite the following sets in words and then in list notation.

a) K= {yy=3x-1, 0 x < 4, x is an integer}

b) M = {x: x =2k, k N}

2
c) N = {x: x < 10, x is an integer}

Example 5: Rewrite the following sets in set - builder notation.

a) A = {1, 4 ,9, 16, 25, 36}

You can write
a set in
different set-builder
b) B = {0 ,3 ,6 ,9 ,12 ,15} forms
