range

It represents all possible output values.

domain

The set of all possible input values.

function

A relation that assigns each input exactly one output, often expressed as an equation.

relation

A relationship between sets of values, where each input corresponds to one or more outputs.

inequality

A mathematical statement that compares two expressions using <, >, ≤, ≥, or is not equal to.

compound inequality

An inequality that combines two or more inequalities, typically using "and" or "or" to define a range of values.
