Final answer:
The given relation is a function.
Step-by-step explanation:
A relation is a set of ordered pairs in which each input (x-value) is paired with exactly one output (y-value). In order for a relation to be a function, each input must be paired with only one output. To determine if the given relation is a function, we need to check if any input has multiple outputs.
In this case, each input (x-value) is paired with a unique output (y-value), which means that there are no inputs with multiple outputs. Therefore, the given relation is a function.
The relation can be represented as a set of ordered pairs: {(5,2), (3,-2), (8,8), (2,-4), (4,0)}
