Yes, I can help you determine if the given relation is a function. To check if a relation is a function, we need to make sure that each input (x-value) has only one output (y-value).
In this case, we have (1, -2), (1, -3), (2, 1), and (3, -2) as the pairs in the relation. Notice that for x=1, we have two different y-values (-2 and -3). Since x=1 has more than one corresponding y-value, the given relation is not a function.
Therefore, the answer is no, the given relation is not a function.
a function is a set of ordered pairs where no two 2nd elements are related to the same 1st element.
So, it is not a function if more than one pair have the same 1st element.
Look at the numbers and you can get the answer.
