- I've been stumped by this problem and can't seem to figure out a way to tackle it.
-
- It goes like this:
-
- Characterize the functions f: X --> Y for which P(X) --> P(Y), F(A)=f(A), is
-
- a)injective,
-
- b)surjective, or
-
- c)bijective.
-
- Would appreciate if somebody threw some light on it. Thanks.
