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
<em>Conclusively, it is a one-to-one function</em>
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.
<em>Hence, this is a function.</em>
