Question 1038999: The domain of f(x) is the set of all real values except 7, and the domain of g(x) is the set of all real values except –3. Which of the following describes the domain of (gof)(x)
all real values except x cannot equal -3 and he x for which f(x) cannot equal 7
all real values except x cannot equal -3 and the x for which f(x) cannot equal -3
all real values except x cannot equal 7 and the x for which f(x) cannot equal 7
all real values except x cannot equal 7 and the x or which f(x) cannot equal -3
