Best ResponseYou've already chosen the best response.1\[f(g(x))=f(10x+6)=7(10x+6)+4\] then some algebra to clean up the answer

Best ResponseYou've already chosen the best response.1look at the steps i wrote first i wrote \(f(g(x))\) then i replaced \(g(x)\) by your \(g(x)\) namely \(10x+7\)

Best ResponseYou've already chosen the best response.1the solution is \[f(g(x))=f(10x+6)=7(10x+6)+4=70x+42+4=70x+46\]
