Are the following mapings automorphisms of their respective groups

[From: ] [author: ] [Date: 11-11-07] [Hit: ]
T is not 1-1, and thus not an isomorphism.b) Since G is not abelian T(xy) = (xy)^(-1) is different from x^(-1) y^(-1) = T(x) T(y).Hence, T is not even a homomorphism.I hope this helps!......
a) G cyclic group of order 12, T:x -> x^3
b) G is the group S3, T: x -> x^-1
