Include the definition 

f[x_]  = "N/A"

This will cover any case not otherwise addressed by the definitions for f.

Hello,

In Mathematica when a function returns unevaluated the "return value"
is the name of the function with arguments.
How do we control such output? Can we suppress it? How do we change
the usual string for something like "N/A"?
Advise please.

Alex
