3.Define the sets A, B, C, and D as follows:

A = {-3, 0, 1, 4, 17}

B = {-12, -5, 1, 4, 6}

C = {x Z: x is odd}

D = {x Z: x is positive}

For each of the following set expressions, INDICATE WHETHER SET IS INFINITE OR FINITE FOR EACH (a-f)

a. A B

b.A B

c.A C

d.A (B C)

e.A B C

f.A C

e. (A B) C

f.A (C D)
