B = {x : x is an integer and –4 < x < 6}.

Question

Write the following sets in roster from: 

B = {x : x is an integer and –4 < x < 6}.

Answer 1

Integers = …-6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7,… 

The elements of this set are -3, -2, -1, 0, 1, 2, 3, 4 and 5 only. 

So, B = {-3, -2, -1, 0, 1, 2, 3, 4, 5}
