Question

Can someone please help me with this question!

Answer 1

see explanation

Explanation:

For the relationship to be a function then each value of x must map to exactly one unique value of y.

This is true for the points except Z andT, where

x → 3 (Z) and x → 5 (T)

This means the relation is not a function

Answer 2

The graph does not represent a function because there are 2 points on the same axis ( T , Z)
