Question

That would be the union of set A and set B wouldn't it?

Answer 2

yes

Answer 3

thats the question

Answer 4

Right but union in math really just means the same thing as it does in English 'to join'.

Answer 5

What do you get when you join A and B?

Answer 6

integers

Answer 7

Answer 12

i quit lol

Answer 13

No don't quit

Answer 14

YOu almost got it

Answer 15

Think of it like this A U B is like saying A joined with B. If A was a set of red marbles and B was a set of blue marbles what would the set of A U B consist of?

Answer 16

blue and red

Answer 17

Correct. Joining them does not change their form to purple or something. We still have red and blue marbles. So apply that to a small set of numbers A={1,3,5} and B={2,4,6}. Now what is A U B?

Answer 18

123456

Answer 19

Right now expand that to a larger set A={all even numbers} and B={all odd numbers}. Now what is A U B?

Answer 20

123456789 ...ect.

Answer 21

Right or {all numbers}. Now just apply the appropriate terminaology (i.e. that used in your question), and you have your answer.

Answer 22

If A={negative even integers} and B={negative odd integers} what does A U B contain?
