## wen_21 Group Title find the function f(x)= x+(1/x), g(x)=x+14/x+2 (fog)(x)= (gof)(x)= (fof)(x)= (gog)(x)= one year ago one year ago

1. RyanL. Group Title

what does "fog" mean?

2. abb0t Group Title

f(x) composed of g(x).

3. RyanL. Group Title

right that means f(g(x))

4. RyanL. Group Title

That means that for all the "x" f(x) we replace with g(x) but we know that g(x)= x+14/x+2 so we replace with that instead.

5. abb0t Group Title

ohhhhh. i get it now!!

6. wen_21 Group Title

$so \frac{ x+14 }{ x+2 } + \frac{ 1 }{ x+14/x+2} ?$

7. RyanL. Group Title

yeah that's basically it. You can simplify it and rewrite it if your teacher told you to.

8. RyanL. Group Title

(gof)(x) is the other way around. That means that for all the "x" g(x) we replace with f(x)

9. wen_21 Group Title

could you give me a hand with simplifying the g(f(x))

10. RyanL. Group Title

I don't think we can simplify it even further. :/
