To show that the functions \( F: \mathbb{R} \times \mathbb{R} \to \mathbb{R} \) given by \( F(a, b) = \max\{a, b\} \) and \( G: \mathbb{R} \times \mathbb{R} \to \mathbb{R} \) given by \( G(a, b) = \min\{a, b\} \) are binary operations, we need to verify that for any two real numbers \( a \) and \( b \), the results of these operations also yield a real number. ### Step 1: Show that \( F(a, b) = \max\{a, b\} \) is a binary operation. 1. **Definition of Binary Operation**: A binary operation on a set \( S \) is a function that combines two elements of \( S \) to produce another element of \( S \). 2. **Consider any two real numbers \( a \) and \( b \)**: Since \( a \) and \( b \) are real numbers, we have \( a, b \in \mathbb{R} \). ...
