Problem
Let 
be a function with the two properties:
- (a) for any two real numbers
and 
, 
, and - (b)
.
and 
, 
, and
.What is the value of 
?
Solution
![\[f(1998 + 0) = 1998 + f(0) = 2000 \Rightarrow \mathrm{(E)}\]](http://latex.artofproblemsolving.com/5/d/6/5d6457cf917203b3385c143415523c45f121254a.png)
