Understanding Relations and Functions - A Comprehensive Guide

🔍Relations and functions are fundamental concepts in mathematics.

✅A relation is a set of ordered pairs, while a function is a special type of relation with unique output values for each input value.

📏The domain of a function refers to the set of input values, while the range refers to the set of output values.

🔄Functions can be represented using various notations, such as mapping diagrams, tables, graphs, and algebraic expressions.

💡Understanding relations and functions is essential in various fields, including calculus, algebra, and computer science.
