Answer:
c. (2, 5) or d. (6, 6).
Step-by-step explanation:
A function is a relation that associates each element x of a set X, to a single element y of another set Y.
Set X is called DOMAIN
Set Y is called RANGE (CODOMAIN)
We have:
{(3, 5), (2, 4), (-3, 0), (6, 3)}
DOMAIN: {3, 2, -3, 6}
RANGE: {5, 4, 0, 3}
If Selwyn adds the pair (2, 5) or (6, 6), then the set is no longer a function, because for
x = 2 we have two different values of y: 4 and 5
x = 6 we have two different values of y: 3 and 6.
