Select the answers that best complete the given statements. Any set of ordered pairs is called a function. domain. variable. range.

Any set of ordered pairs is called a function. Functions are special types of relationships where each input (or domain value) maps to exactly one output (or range value). Think of it like a vending machine: when you press a button (input), you get a specific snack (output) every time! The ordered pairs also define a relationship between a domain (the set of all first elements) and a range (the set of all second elements). For example, if you have pairs like (1,2), (2,3), and (3,4), the domain is {1, 2, 3} and the range is {2, 3, 4}. This clear structure helps you visualize mathematical relationships!
