Could you me with one algebra problem?
construct the appropriate number sets with the given information. use the sets to match the following:
given
a = ø
b = b
c = then a ∪ b = b
d = a
e = then a ∩ b = b
i have to match these options:
1. if ab
2. if ba
3. a ∪ ø
4. a ∩ ø
5. b ∪ ø
with these options:
c
a
d
b
e
