Question:
A relation $R$ on set $A = \{1, 2, 3\}$ defined by $R = \{(1,1), (2,2), (3,3), (1,2), (2,3)\}$ is: (a) Reflexive only (b) Equivalence relation (c) Symmetric (d) Transitive
Step-by-Step Solution
Key Concept: (2,1) not in R => not symmetric. (1,2),(2,3) in R but (1,3) not in R => not transitive.
The detailed step-by-step mathematical proof is available inside the Mathbee app workspace.
