How do I find g(x) if f(x) = x+1/x and f o g(x) = 3x+1?
I've gotten as far as g(x) + 1 = g(x)(3x + 1)
What do I have to do next?
Thanks for the help!
That should be on the left.
Think of g(x) as being a variable itself rather than a function:What do I have to do next?

f(g)= g+ 1/g= 3x+1. Now solve for g. Multiplying both sides by g gives , a quadratic equation. Use the quadratic formula to solve for all x.
