Please answer the questions in bold. Thank you! Will rate.

1.A = {x Z: x is even}

C = {3, 5, 9, 12, 15, 16} D = {5, 7, 8, 12, 13, 15}

The universal set U is the set of all integers. Select the set corresponding to

a. {3, 9}

b.{5, 7, 13, 15}

c.{8, 12}

2.Use the definitions below to select the statement that is true.

A = {x Z: x is even}

B = {x Z: 4

a. A A

b. B

c.A is finite

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 the set is infinite or finite.

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)
