If (A={1,2,3,4}) and (R={(a,b):\min(a,b)=a}), what is (R) with respect to reflexivity?

Answer and explanation

Correct answer: Reflexive

Step 1: On the diagonal, (\min(a,a)=a). Step 2: This is true for every (a\in A), so all ((a,a)) are in the relation. Step 3: For minimum and maximum conditions, substitute equal elements first.
