Looking for some assistance

Looking for some help on this one....

Given relation schema R(A,B,C,D,E,F,G,H,I), and given the set of functional dependencies:

AB-->CD
A-->E
B-->FH
C-->G
D-->B
G-->C
H-->I

What is the key for this relation schema? AND what normal form is this schema in?
Then, if it's not in 3NF, decompose the schema into a set of 3NF schemas.
