Determine whether the relation is reflexive, symmetric, and/or transitive?
Let R be the relation on the set ‘N’ of strictly positive integers, where strictly positive integers x and y satisfy x R y iff x^2 – y^2 = 2^k for some non-negative integer k. Which of the following statement is true with respect to R? I think it’s just reflexive, because it obeys reflexive conditions.
