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!
