Question 140680
given that
---------------
 f(x) = x^2+x+2
-----------------
 g(x) = x^4-x
---------------
what are 
1. f(g(x))

= f[x^4-x] = [x^4-x]^2 + [x^4-x] +2
----------------------------------------
2. g(f(x))
= g[x^2+x+2] = [x^2+x+2]^4 -[x^2+x+2]
-----------------------------------------
3. f(f(x))
= f[x^2+x+2] = [x^2+x+2]^2 + [x^2+x+2] + 2
etc.
I hope you can see how these are done.
Cheers,
Stan H.


4. g(g(x))
5. g(f(g(x)))
