Simple Manipulations of Functions

The mathematica manuals do not seem to give easily
decipherable clues as to how to employ commands such
as Conjugate, Re, Im, etc. when the argument is anything
other than a number.  So, if I type in

f[x_]=Exp[I x]
g[x_]=Conjugate[f[x]]

how do I get mathematica to return to me the expression

Out: g=Exp[-I x]

instead of merely returning my input verbatim?

Thanks for the help!
