Question

find the cardinality and write the roster form of given set : p={x:x and x+3 < 9}

Answer 1

given,

p={x:x and x+3 < 9}

so, given x+3< 9

=> x< 9-3

=> x< 6

so, if x is in set of natural number , the set is :

P={1,2,3,4,5}

n(p) = 5

if x is in set of whole number, the set is

P={0,1,2,3,4,5}

n(P)= 6

if x is in set of integers, the set is:

P={5,4,3,2,1,0,-1,-2,-3...}

n(p)= infinity
