if A= {xlx is odd} amd B={xlx>7} list the elements of A union B
CORRECTION LIST THE ELMENETS OF A AND B NOT A UNION B
9, 11, 13, etc
written as (9,infinity)..I don't know how to make the infinity symbol here
To list the elements of A union B, we need to find all the elements that are in either set A or set B (or both).
Set A is defined as {x | x is odd}. This means that any odd number would be an element of set A.
Set B is defined as {x | x > 7}. This means that any number greater than 7 would be an element of set B.
To find the elements of A union B, we need to identify all the numbers that are either odd or greater than 7 (or both).
Here are some elements that would be part of A union B:
Odd numbers: 1, 3, 5, 7, 9, 11, 13, 15, ...
Numbers greater than 7: 8, 9, 10, 11, 12, 13, 14, 15, ...
Combining both sets, we can see that the elements of A union B would include:
1, 3, 5, 7, 8, 9, 10, 11, 12, 13, 14, 15, ...
