Hi Arun,
Roster form means writing a set with all its elements.
Example -
A = {x: x is an integer and –3 < x < 7}
Represent A in roster form.
So, we find all elements of set A
We know that
Integers = ......-4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10….
The elements of this set are –2, –1, 0, 1, 2, 3, 4, 5, and 6 only.
Thus, set A in roster form is A = {–2, –1, 0, 1, 2, 3, 4, 5, 6}
