The problem involves finding the values of inverse functions given specific mappings of a one-to-one function. The original poster provides values for f(22) and f^-1(13) and seeks to determine f^-1(9) and f(7).
Participants are exploring the definitions and implications of inverse functions, with some providing insights into the mapping relationships. There is an ongoing inquiry into the meaning of the mappings provided and how they relate to finding the desired values.
There is a lack of explicit equations for the functions involved, which may affect the ability to derive the required values. The discussion is framed within the constraints of one-to-one functions.

steve snash said:Homework Statement
f(22)=9 and f^-1(13)=7
find f^-1(9) and f(7)
(given that these are 1-1 functions)
Homework Equations
What does this mean as the have not given the equations they used to find the values, i know inverse function is the function that can find the opposite of the original function.
