Question

write the roaster form of set A ={x/-3 < x <3 and x€Z​

Answer 1

Answer:

Since, x/-3 < x. Hence, no -x€Z is possible.

So, we look for +x€Z: x<3

Hence, A= {1,2}

3 is not possible as it is not less than 3. Had, x is less than or equal to 3, then 3 would have one component of the set. 0 is not possible as 0/-3 = 0 is not less than 0 which is the given condition.
