If a function is even ie if f(-x) = f(x). Such a function would be symmetric about the y-axis. So f(x) is a many-to-one function. The inverse mapping then is one-to-many which is not a function.
In fact, the function need not be symmetric about the y-axis. Symmetry about x=k (for any constant k) would also do.
Also, leaving aside the question of symmetry, the existence of an inverse depends on the domain over which the original function is defined. Thus, y = f(x) = x2 does not have an inverse if f is defined from the real numbers (R) to R. But if it is defined from (and to) the non-negative Reals there is an inverse - the square-root function.

What kind of symmetry does an odd function have?
Reflection about the y-axis.
IS the rational function to study the relationships of inverse variation?
A study of inverse relationships is one of a very large number of uses for rational functions. Only a rational function of a very special kind will be of any use.
