Question

Let S={-2,-2,0,1,2,3}. Describe each of the following sets as: {xES : p(x)} where p(x) is some condition on x

Answer 1

So where are they?

Answer 2

between -2 and 3

Answer 3

That's not a set

Answer 4

these are elements of the set...

Answer 5

So what does "between" mean?

Answer 6

S is the set of elements {-2,...3} I meant that

Answer 7

"Describe each of the following sets"

I am asking where are the 'following sets'....:-(

Answer 8

;/ sorry...
A= {1,2,3}, B={0,1,2,3}, C={-2,-1}, D={-2,2,3}

Answer 9

So to get a p(x) you find some property of th elements that they have in common but that are not common with the other members in S

eg the set A contains positive integers and the other members of S are not positive integers so that's a good description.
and you would say {x in S : x is positive integer}
