- Domain: List of x-values that are possible in a relation.
- Range: List of y values that are possible in a relation.
So firstly, looking at our table, we see that the Domain is {0, 1, 2, 3} and the Range is {-3, -2, 2, 5}
Next, what makes a relation a function is that every input (x) has only one output (y). Since this table has every x value only have 1 y value, this relation is a function.
Putting it all together, the correct option is the last option.
