expanding sums



Having defined the general term of series of functions this way: 
f[n](x):=(1/n!)*x^n;
i would like to expand a few terms, e.g. between 0 and 4 or between 5 and 8
on one line

The command 
  sum(f[n](1/4),n,0,4);
seems of no use, since only the final result is returned.

The only way i know is through a for-loop 
  for n: 0 thru 4 do disp(f[n](x));
listing terms in a column.

Any possibility to display the terms on one line?

thank you
