CSS 220 Module 4 Homework
MORE SET APPLICATIONS:
1. Write the following sets in the set builder form.
o B = {3, 9, 27, 81}
B = {x : x N, x = 3
p
, p N, 1 p 4}
o E = {4, 6, 8, 10, 12, 14, 16, 18, 20, ......., 52}
E = {x : x N, x = 4 + 2p, p N, 0 p 24}
o F = {-10, ......, -3, -2, -1, 0, 1, 2, …..., 5}
F = {x : x Z, -10 x 5}
2. Write the following sets in the roster form.
o A = {x : x N, x ≤ 5}
A = {0, 1, 2, 3, 4, 5}
o B = {x : x Z, -3 < x < 3)
B = {-2, -1, 0, 1, 2}
o C = {x : x Z, x is divisible by 12}
C = {…, -36, -24, -12, 0, 12, 24, 36, …}
o D = {x : x Z, x = 3p, p Z, p ≤ 3}
D = {…, -9, -6, -3, 0, 3, 6, 9}
The answers to 3 through 12 will be one of the following: A, U, B, , or their compliments.
3. A = A
4. A ∩ U = A
5. A A
c
= U
6. A ∩ A
c
=
7. U
c
=
8.
c
= U
9. A U = U
10. A =
11. A ∩ (A B) = A
12. A (A ∩ B) = A
