How do you find the inverse of f(x)=7f(x)=7?

This function has no inverse since it is not one to one.

Explanation:

Strictly speaking, the function f(x) = 7f(x)=7 only has an inverse if its domain has at most one element.

However, we usually assume a default domain such as the Real numbers, RR, for which f(x) is not one-one. For example, f(0) = f(1) = 7, so f^(-1)(7) would not be well defined.
