To show that the relation \( R \) defined on the set of real numbers as \( R = \{(a, b) : a \leq b^2\} \) is neither reflexive, nor symmetric, nor transitive, we will analyze each property step by step. ### Step 1: Check for Reflexivity A relation \( R \) is reflexive if for every element \( a \) in the set, the pair \( (a, a) \) belongs to \( R \). This means we need to check if \( a \leq a^2 \) holds for all real numbers \( a \). 1. **Consider the inequality**: \[ a \leq a^2 ...
