and
.
Step-by-step explanation:
To this relation be a function, the horizontal coordinates can't be equal. So, let's find the value of
that makes those coordinates equal.

Using the null factor property, we have

Therefore, the given relation is not a function when
and
.
You have

So, we have to compute g(7) and feed it as input to f(x). We have
