(adsbygoogle = window.adsbygoogle || []).push({}); Finding the inverse of a function???

1. The problem statement, all variables and given/known data

Find (f^-1)'(a), a =2

√(x^3 + x^2 +x +1)

So, if a = 2, then f^-1(2) = 1 and f(1) = 2

2. Relevant equations

3. The attempt at a solution

I figured out that f(1) = 2,

so

√(3(1)^2 + 2(1) + 1)

= √6

so the final answer I got was 1/√(6)

?
