Answer with explanation:

Ordered Pair = {(–8, –6), (–5, 2), (–8, 1), (7, 3)}

Preimage (x) Image(y)

-8 -6

-5 2

-8 1

7 3

Element , -8 more than 1 image that is , -6 and 1.

→→So, if an element in a set that is in preimage, has more than one image then that relation is not a function.

So, the given relation is not a function.

⇒→Ordered Pair ={(–3, –6), (–1, –6), (5, –6), (8, –6)}

Preimage (x) Image(y)

-3 -6

-1 -6

5 -6

8 -6

All the elements in preimage has same image that is , -6.No two same element in preimage has more than one image.

So, the given relation is a function.

So, the relation is a Function.
