Best ResponseYou've already chosen the best response.2first step is to solve g(x) when x = 2 then take the result and plug it into f(x)

Best ResponseYou've already chosen the best response.2... huh? let's take it one step at a time: what is g(x) when x = 2?

Best ResponseYou've already chosen the best response.0okay so g(2)=2x3 what do I do next with this funtion? @Vocaloid

Best ResponseYou've already chosen the best response.2yup! g(2) = 7 alright, so now let's plug in 7 for x using f(x)

Best ResponseYou've already chosen the best response.2if x = 7, what is f(x)?

Best ResponseYou've already chosen the best response.0oh that was my fault I plugged it in for the wrong problem @Vocaloid

Best ResponseYou've already chosen the best response.0instead of the x it would be F(7) Am I right? @Vocaloid

Best ResponseYou've already chosen the best response.0F(7)=7+4 F(7)=3 what am I going to use F(7) for? @Vocaloid

Best ResponseYou've already chosen the best response.2not quite, check your math again f(7) = (7) + 4 = ?

Best ResponseYou've already chosen the best response.0F(7)=7+4 F(7)=3 F(g(2))=7 right? :) @vocaloid

Best ResponseYou've already chosen the best response.2well, ok, we know that f(7) = (7) + 4, right? (7) = 7, so f(x) = 7 + 4 = 11 11 is our answer

Best ResponseYou've already chosen the best response.2full explanation: the question asked for f(g(x)) when x = 2 that means, plug in 2 for x to find g(2) g(2) = 7, so we plug in 7 for x in f(x) f(7) = 11, meaning f(g(2)) = 11

Best ResponseYou've already chosen the best response.0but how did you get that negative in front of the perentheses

Best ResponseYou've already chosen the best response.2f(x) = x+4 x = 7 f(x) = (7) + 4

Best ResponseYou've already chosen the best response.0oh so the negative of the other x was still be in play
