Question 927417: What are all the subsets of the set {-1,9}?
Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! What are all the subsets of the set {-1,9}?
------------------------
No elements:: null set
One element:: {-1} and {9}
Two elements: {-1,9}
-----------------
Note:: A set with "n" elements always has 2^n subsets.
