Answer:
The relation is a function.
Step-by-step explanation:
A mathematical function is a relation that is established between two sets, through which each element of the first set is assigned a single element of the second set or none.
Therefore, given a set A and a set B, a function is the association that occurs when each element of set A is assigned a single element of set B.
The relation {(-2, -4), (- 1, -4), (3, -4), (6, -4)} contains the following sets:
A = {-2, -1, 3, 6}
B = {-4}
The relation is a function because each element of set A corresponds to a single element of set B, that is, no element of set A is repeated, all of them are different. The fact that set B contains a single element does not influence, so that the relation is a function.
Hope this helps!
