1. The question is: P on the set, A, of all people, where xPy means x is a parent of y. 2. Relevant equations - None 3. Attempts at a Solution Here is where I am confused. Reflexivity is defined by aRa. So I am unclear what to do with more than one variable. So in this question, do I examine if xRx? That is to say is x a parent of x? If that is the case, then the answer is clearly no. I am just unsure of how to deal with reflexivity. I am ok with symmetry and transitivity.
