Characteristics of Functions
For each of the following relations, explain why they are or are not a function using complete sentences.
Domain: 15
Range: 2.
1 answer
This relation is not a function because there is only one element in the domain (15) but multiple elements in the range (2). In order for a relation to be a function, each element in the domain must have a unique element in the range.
