The question I have is:

The function $\displaystyle f$ has domain $\displaystyle [1, \infty]$ and is defined by

$\displaystyle f(x)$ = $\displaystyle ln (5x - 4) + 2$.

The question wants

a] an expression for $\displaystyle f^{-1}(x)$

b] statement of the domain and range of $\displaystyle f^{-1}(x)$.

I am trying to learn how to solve questions such as these, however I have no resources from which to learn it so it's very difficult not knowing how to do something without a lot of outside help!

How would you solve this problem? If possible, is there any website that you could find that may help with this topic as I have tried looking and failed to find anything relating to it whatsoever
