Answer:
"This relation is not a function as the domain has fewer values than the range, so there must be a domain value which maps to more than one range value."
Explanation:
If each element of the domain has a unique value inside the range, the relation is said to be a function.
A relation's domain is a collection of all whole numbers in the range of 2.5 and 7.5, with a total of 6 distinct values.
The range of whole numbers from 2.5 to 7.5 is 3, 4,5,6,7
There must be a domain value that maps to more than one range value since this relation is not a function because the domain contains fewer values than the range.
