For the following functions, f and g, determine
(a) f(g(x)) (b) g(f(x))
If f(x)= 7x+4 and g(x)10x+6 , then

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.0okay from the basic algebra how do we find f(g(x))?

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.0so I got this: 70X + 46 = 70X40

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