Decide whether the relation is a function or not
{(-4, -8), (-1, 2), (2, -2), (6, 1)}
To determine if the relation is a function or not, we need to check if each input (x-value) is paired with only one output (y-value).
We can approach this problem by creating a set of all the x-values in the relation. If there are no repeated x-values, then the relation is a function.
Let's identify the x-values in the given relation: -4, -1, 2, 6.
There are no repeated x-values; each x-value appears only once in the relation. Therefore, this relation is a function.
