Determine if each relation is a relation or not

A function is represented as:

Where

and

For a relation to be a function:

No x value (in other words, the domain) must be repeated

The above relation is a function. This is so because every unique value of x have a unique value of y.

In other words:

No two domains exist for a range

Conclusively, it is a one-to-one function

In the above table, we have:

and

The domain (-2) points to range (5 and -1).

Based on the condition that no two domain should point to the same range, we can conclude that this is not a function.

In the above table, we have the domain to be:

We can see that no x value is repeated.

Hence, this is a function.
