Answer:
Domain of a function means the set of values of the variable for which the given function exists.
(g circle f) (x) means g{f(x)}.
g{f(x)} will exists for all the real values of x except x = 7 and that particular x for which f(x) = -3.
Hence the domain of g{f(x)} will be all real values except x = 7 and the x for which f(x) = -3
