### Grade 8 - Mathematics4.27 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. 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.
 Q 1: A = {1,4,9,16,25}, write this in set builder form.A = {x2/x Î N, x < 6}A = {x2/x Î N, x > 6}A = {x2/x Î N, x = 6} Q 2: E = {-4,-3,-2,-1,0,1,2,3,4}, write this in set builder form.E = {x/x Î Integers, -5 = x = 5}E = {x/x Î Integers, -5 < x < 5}E = {x/x Î Integers, -5 > x < 5} Q 3: Q = {0,1,2,3,4,5,6}, write this in set builder form.Q = {x/x is a whole number and x < 7}Q = {x/x is a whole number and x > 7}Q = {x/x is a whole number and x = 7} Q 4: B = {1,3,5,7,9,11,13}, write this in set builder form.B = {x/x is an odd number x > 14}B = {x/x is an odd number x = 14}B = {x/x is an odd number x < 14} Question 5: This question is available to subscribers only!
