Usually, Mathematica returns a syntacticly correct expression
unevaluated when it does not know what to do with it. Plot will return
some pair of axes. For instance, if one evaluate the following
expressions, f[x] is a function without any definition and Plot just
draws a pair of axes.
ClearAll[f] (* To be sure that f will not be defined. *)
Plot[f[x], {x, 0, 10}]
