HELP PLEASE!!!:
f(x)=3x4
g(x)=x^2
1.(f o g)(2)
2.(f o f)(2)
f(x)=2x
g(x)=x^2+2
h(x)=4x+3

Best ResponseYou've already chosen the best response.0for the first part, what does the 2 do? i know how to solve (f o g)(x)

Best ResponseYou've already chosen the best response.1(f o f)(2) is basically saying f( f(2) ), in other words, in 3x4, replace x with ( 3x  4 ) so you get f o f(2) = 3( 3(2)  4 )  4 then simplify.

Best ResponseYou've already chosen the best response.0like h(f(x)(g(x))? but then how do i solve it

Best ResponseYou've already chosen the best response.1(h o f)(x) = h(f(x)) so (h o f)o g = h(f(x)) o g = h( f ( g(x) ) ) f(g(x)) = 2(x^2+2) so h ( f ( g ( x ) ) ) = 4(2(x^2+2) )+3 Is this clear enough?

Best ResponseYou've already chosen the best response.0wait but if f o g would nt it be h(f(x)(g(x))

Best ResponseYou've already chosen the best response.0h o f is h(f(x)) and then there's o g so wouldnt it be h(f(x)(g(x))

Best ResponseYou've already chosen the best response.1Well, h o f o g = h( f( g(x) ) ) Basically (h o f) o g is same since h and f go first anyway.
