It looks like you are done. I don't see anything else you are supposed to do unless there is more to the question you didn't post. Do you need to find the inverse of g(x) too?

ok i will post the question in order..
1. find $\displaystyle f^{-1} x$
2.determine the value of x which $\displaystyle f^{-1} x=x$
Since you had already determined that [tex]f^{-1}(x)= \frac{x}{5}- 2, determining x such that $\displaystyle f^{-1}(x)= x$ just means solving $\displaystyle \frac{x}{5}- 2= x$.
