Answer

A relation is any set of ordered pairs, and a function is a special kind of relation where each first coordinate is unique.

Solution

A relation is any set of ordered pairs. A function, on the other hand, is a special kind of relation with an extra requirement: for each \( x \) in the domain, there is exactly one \( y \) associated with it. In other words, a function is a relation in which no two different ordered pairs have the same first coordinate. Thus, the correct answer is: - A relation is a set of ordered pairs; a function is a special kind of relation in which no two ordered pairs have the same first coordinate.

The Deep Dive

Let's dive into the fascinating world of mathematics! A relation consists of a set of ordered pairs, which can map one element from a first set to one or more elements in a second set. However, a function is a special type of relation where each input (or first coordinate) corresponds to exactly one output (or second coordinate). So, in essence, all functions are relations, but not all relations are functions! To keep your math game strong, remember this handy tip: when trying to determine if a relation is a function, you can use the "vertical line test" on its graph. If a vertical line intersects the graph at more than one point, it’s not a function. This visual approach can help avoid common mistakes in identifying functions, especially if you're dealing with complex relations!
