WebArgue why an equivalence relation that is also a function must be the identity. The identity I : A !A is defined by I(a) = a for all a 2A. Solution Let R be an equivalence relation on A and a function R : A !A. Then by the definition of a function, for every a 2A, there is one and only one b 2A so that (a;b) 2R, which means that aRb. crewel work company seconds
