Question

If A = {integers divisible by 2} and B = {integers}, what is A ∩ B?

{…−3, −2, −1, 0, 1, 2, 3 …}

{ }

{0}

{… −6, −4, −2, 0, 2, 4, 6 …}

Answer 1

A=even numbers= {… −6, −4, −2, 0, 2, 4, 6 …}
B=all integers={…−3, −2, −1, 0, 1, 2, 3 …}

now what do u think? what will be A ∩ B using the fact that A is a subset of B

Answer 2

{ } ?

Answer 3

answer is {… −6, −4, −2, 0, 2, 4, 6 …}

Answer 4
