Answer:
The set of all real values except 7
Step-by-step explanation:
We are given that,
Domain of the function f(x) is 'the set of all real values except 7'.
Domain of the function g(x) is 'the set of all real values except -3'.
It is required to find the domain of
.
Now, we know that,
<em>The composition
of functions
and
will be defined where the function
is defined.</em>
Since, the domain of f(x) is 'the set of all real values except 7'.
Thus, the domain of
is also 'the set of all real values except 7'.
