this is my stab A map f from A to B: f: A --> B is a subset of AxB such that if a : A there exists b : B such that (a,b) : f if (a,b) : f and (a,c) : f then b=c if (a,b) : f we say a maps to b (under f?): f a -> b wikipedia goes with:

$A function with domain X and codomain Y is a binary relation R between X and Y that satisfies the two following conditions:[10] For every x {\displaystyle x} in X {\displaystyle X} there exists y {\displaystyle y} in Y {\displaystyle Y} such that ( x , y ) ∈ R . {\displaystyle (x,y)\in R.} If ( x , y ) ∈ R {\displaystyle (x,y)\in R} and ( x , z ) ∈ R , {\displaystyle (x,z)\in R,} then y = z . {\displaystyle y=z.}$
