Answer:
4x + 3y = 12
Step-by-step explanation:
These are just sketches, you should polish them yourself. In analogy to relations, I will write aFb to mean the statement f(a) = b.
(a) aFa, so f(a) = a. This is the definition of the identity function.
(b) aFb => bFa, so f(a) = b and f(b) = a. Therefore f(f(a)) = a by substitution, and hence f^2 is the identity function.
(c) aFb and bFc => aFc. So f(f(a)) = c, and f(a) = c. Thus f(c) = c, which is the identity. Make sure you sort out the im(F) stuff when you clean this up.
