STEP 1: Recall how to choose the correct mapping diagram for the ordered pairs given

STEP 2: Draw the mapping diagram

STEP 3: Recall when is a relation said to be a function. A relation is said to be a function when the domain is not repeated more than once. As you can see the number 5 is repeated twice and the number 2 is also repeated twice in the set of ordered pairs given and the mapping diagram drawn.

So, the given relation is not a function.
