Answer:
{(-8,-8), (9, 9),(4,5), (4,0)}
Step-by-step explanation:
A relation that is a function does not have any repeating x-values.
A function has one input assigned to <u>exactly one</u> output.
The x-value of 4 repeats in the top set:
{(-8,-8), (9, 9),(4,5), (4,0)}
Therefore, the set is<u> not a function</u>.
