Answer:
Third choice
Step-by-step explanation:
The domain of f(x) is the set of all real values except 7, i.e [tex]x\ne7[/tex]
and the domain of g(x) is the set of all real values except -3, i.e [tex]x\ne -3[/tex]
The domain of [tex]g\circ f[/tex] is the set of all real numbers x in the domain of [tex]f[/tex] such that [tex]f(x)[/tex] is in the domain of [tex]g(x)[/tex].
However any numbers that are excluded from the domain of f must also be excluded from the domain of [tex]g\circ f[/tex].
Therefore the correct choice is all real values except x=7 and the x for which f(x) =7
Answer:
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
the right answer is all real values except x = 7 and the x for which f(x) = -3
