Which description best explains the domain of (gºf)(x)?
the elements in the domain of f(x) for which g(f(x)) is defined
the elements in the domain of f(x) for which g({(x)) is not zero
the elements in the domain of g(x) for which g{{(x)) is defined
the elements in the domain of g(x) for which tr(x)) is not zero
o
A. The elements in the domain of f(x) for which g(f(x)) is defined
I just took the test myself. (gºf)(x) can be rewritten as g(f(x)) and the interior function, which is f(x) in this case, is the domain, where x is defined.
