    f(x)?

    Undergrad Inverse of s(x)=[1+f(x)]/[1-f(x)]

    I found the answer on wolfram alpha, I can invert normal functions but this one has me totally stumped.

    Undergrad Inverse of s(x)=[1+f(x)]/[1-f(x)]

    really have no idea where to start..

    Undergrad Inverse of s(x)=[1+f(x)]/[1-f(x)]

    (1+s(x))/1-s(x)?

    Undergrad Inverse of s(x)=[1+f(x)]/[1-f(x)]

    Is s-1 a composition of f-1.. I'm definitely missing something silly here...

    Undergrad Inverse of s(x)=[1+f(x)]/[1-f(x)]

    f is a one to one function with inverse f^-1, and we are asked to find the inverse of s(x)=[1+f(x)]/[1-f(x)] My attempts leave me with s^-1(x)= [f^-1(1-x)]/[f^-1(-x-1)] and I don't think this is correct. I can't find any examples of problems like this online.
