Complete the definition. A relation/function is a relation/function where there is exactly one unique output/input for each output/input

A relation has an input value which corresponds to an output value. When each input value has one and only one output value, that relation is a function. Functions can be written as ordered pairs, tables, or graphs. The set of input values is called the domain, and the set of output values is called the range.
