Question

the set of all natural numbers less than 10 change to set builder form and roster form​

Answer 1

Answer:

roaster methd:

{1,2,3,4,5,6,7,8,9}.

set builder form:

{x/x=N,x>10}

Answer 2

Answer:

Roster form : {1,2,3,4,5,6,7,8,9}

Set builder form:  {x/x∈N, x<10}

Step-by-step explanation:

To find,

Express the 'set of all natural numbers less than 10' to set builder form and roster form

Recall the concepts:

To represent a set in roster form, write all the elements of a set in a curly bracket separated by a comma

To represent a set in set builder form, we write the rule that represents the elements in the set

Solution:

Let A be the ' set of all natural numbers less than 10'

The elements in the set are 1,2,3,4,5,6,7,8,9

Roster form representation of this set is

A = {1,2,3,4,5,6,7,8,9}

Set builder form representation of this set is

A = {x/x∈N, x<10}

Answer:

Roster form : {1,2,3,4,5,6,7,8,9}

Set builder form:  {x/x∈N, x<10}
