**Reiny**, Monday, December 15, 2008 at 4:28pmyou can first find g(3) = 10

then do f(1) = 1/10

so g(g(3)) = 1/10

you try the other one.

another way is to find f(g(x)) itself.

this would be practical if you had a whole bunch of question to find

f(g(x))

= 1/(3x+1)

notice the right side gives you 1/10 directly

**Reiny**, Monday, December 15, 2008 at 4:31pmmy third line should have said

f(g(3)) = 1/10

for your last part,

e.g. gºg would mean g(g(x))

= 3(3x+1) + 1

= 9x+ 4
