Let be a function such that for any two real numbers and . If , then what is

I just realised that I could have done this more easily

f(2012+0)=2012+f(0)

f(2012)=2012+2

f(2012)=2014

Umm Interesting

What if x=-2012 and y=2012

f(-2012+2012)=-2012+f(2012)=2

so

-2012+f(2012)=2

f(2012)=2+2012=2014

I think that is it :)

Very nice, Melody.....I'd have no idea how to approach this one !!!!

Thanks Chris.

I had to think about it for a while myself.

You can get some really weird questions that are like this one!
