Question

Directions: Write down the indicated union of sets.

A= { -3 1 5 9 }
B= { -4 -2 0 4 }
C= { -1 3 7 }
1.(B U C)
2.(C U A)
3.(B U A)

Answer 1

1. (B U C) = {-4, -2, 0, 4} U {-1, 3, 7} = {-4, -2, 0, 4, -1, 3, 7}

2. (C U A) = {-1, 3, 7} U {-3, 1, 5, 9} = {-1, 3, 7, -3, 1, 5, 9}

3. (B U A) = {-4, -2, 0, 4} U {-3, 1, 5, 9} = {-4, -2, 0, 4, -3, 1, 5, 9}
