Step 1. Given Information.

A relation: $(1, 2), (1, 5), (2, 4), (3, 3), (4, 1)$

Step 2. Calculation.

Upon graphing our given relation, we will get our required graph as shown below:

The mapping diagram of our given relation would look like:

We know that a relationship will be also a function, when each input in the domain has exactly one specific corresponding output.

Upon looking at our given ordered pairs, we can see that each x-value corresponds to a specific y-value except 1. We can see that 1 corresponds to 2 and 5.

Step 3. Conclusion.

The given relation is not a function.
