Thread: find the formula for the function

f(x)= x^2+1 g(x)=1/(x-3)

f(g(x))

so (1/(x-3))^2 +1

and from there i am lost on this problem.

thanks

Your working out is correct.

You also don't really need to go any further, unless you are asked to write it down in a different way...

This is about as far as you can go, but like I said, what you had so far is also correct.

ok thanks, just got confused over how far i should go, this clears it up for me.
