Answer:
See attachment
Step-by-step explanation:
The relation that is not a function is shown in the attachment.
For a relation to be a function, it must be either one-to-one or many-to-one.
The relation shown in the attachment is one-to-many relation hence it is not a function.
This is because -5 corresponds to -4 and 3,making the graph of this relation to fail the vertical line test.
