Best ResponseYou've already chosen the best response.0the domain of the function f(g(x)) doesnt change any from it component parts. f(x) can use anything ; but g(x) cant use 6 so the domain of the composite is everything but "6"

Best ResponseYou've already chosen the best response.0g(f(x)) would give us an additional ixnay for x... in that we might not be able to use 10

Best ResponseYou've already chosen the best response.0if we were to consider functions that would perhaps"cancel"out an inapproriate domain, then the original domains would still take precident

Best ResponseYou've already chosen the best response.0If \[f(x)=x+4\textrm{ and }g(x)=\frac{9}{x+6}\] then \[(f\circ g)(x)=f(g(x))=\frac{9}{x+6}+4.\] So \[D_{f\circ g}=\mathbb{R}\backslash\{6\}.\]
