Newton-Inverse

Let f(x) be a function which has an inverve f −1(x).You are given the following information about f(x)
f(-3.77988549)=-22.0347673
f'(-3.77988549)=7.05461653

Your task is to find the following values of f −1(x)and (f −1)′(x):

Trial number 1:
f −1(30.7052686)=
(f −1)′(30.7052686)=

Make the best possible guess about these values, given the information provided about this mystery function f(x). After you submit your answers, you will be provided with further clues about the function, which you can use to refine your guesses. You will be scored on the basis of the number of attempts it takes you to find the correct values.
