Determine whether the following relations are injective and/or subjective function. Find universe of the functions if they exist. A = 1,2,3,4,5 B=1,2,3,4,5 R = (1,2),(2,3),(3,4),(4,5),(5,1)

Here's the Solution to this Question
Let us determine whether the relation is an injective function. Since there are no different pairs with the same second coordinate, we conclude that the relation is an injective function.
Taking into account that we conclude that the relation is a surjective function.
It follows that the inverse of exists and it is equal to
