How many linear functions (functions of the form f(x)=ax+b) are equal to their own inverse? Answer with a non-negative integer or with "inf" for "infinitely many."

This is wrong. There are infinitely many linear functions that are an inverse of themselves.

It is correct, could you give us some examples of other inverse functions?
