Graph the relation. is the relation a function? why or why not? {(–1, 1), (–2, 1), (–2, 2), (0, 2)} yes; there is only one domain value for each range value. no; a domain value has two range values. yes; there is only one range value for each domain value. no; a range value has two domain values.

{(–1, 1), (–2, 1), (–2, 2), (0, 2)}  

In a function, each input has an output

Each domain has a range. In a function, range can be repeated but domain cannot be repeated. Same domain cannot have two range values.

Here domain is {-1, -2, -2, 0}

Range is { 1, 1, 2, 2}

Domain -2 is repeating so this relation is not a function

Answer : No; a domain value has two range values.

the correct answer is 1: 2
