anonymous · Answer

Know what  (f(g)) means?

anonymous · Answer

composition of functions right?

anonymous · Answer

Yes.

joftheworld · Answer

yes composite functions

anonymous · Answer

So you are putting the function for g(x) inside of f(x).

joftheworld · Answer

in order to do that you have to find f(g)

joftheworld · Answer

is there anymore info on this problem ?

anonymous · Answer

No there is not anything else thats all it says

anonymous · Answer

You do not need more.  You are given f(x) and g(x).  You just need to replace the x in f(x) with the function part of g(x) and solve.

anonymous · Answer

When you put g(x) into f(x) what do you get?

anonymous · Answer

Here are some examples:
m(x) = 2x+5
n(x) = 3x-1

m(n(x)) = 2(3x-1)+5
m(n(x)) = 6x-2+5
m(n(x)) = 6x+3

n(m(x)) = 3(2x+5)-1
n(m(x)) = 6x+15-1
n(m(x)) = 6x+14

You can see that all I am doing is putting one function into the other distributing and simplifying.
