Answer:
This relation is a function.
Step-by-step explanation:
A function is a process or a relation that associates each element x of a set X, to a single element y of another set Y.
We have
{(-3, -6), (-1, -6), (5, -6), (8, -6)}
x = -3 → y = -6
x = -1 → y = -6
x = 5 → y = -6
x = 8 → y = -6
YES. This relation is a function.
/each x has one value of y/
