If f(x1)+f(x2)=f(x1+x2) for all real numbers x1 and x2, which of the following could define f?
a) f(x)=x+1
b)f(x)=2x
c)f(x)=1/x
d)f(x)=e^x
e)f(x)=x^2
i have no idea how to go about this, if someone can explain it to me.

For the answer to the question above, the answer is simple.
it is multiple choice letter B since f(x1) + f(x2) = 2x1 + 2x2 = 2(x1+x2) = f(x1+x2)
