Math Function Question

[NDroho]

Need some help understanding how to solve this problem. I am a bit lost

F(a+b) = F(a) + F(b) for all positive numbers and a & b.

A) X^2
B) x+1
C) x^(1/2)
D) 2/x
E) -3x

Do I just use numbers and solve? A = 2 and B = 3?

Please post the EXACT WORDS of the problem, EXACTLY as written. This is very important -- if you post even one word of the problem differently, lots of people will be unable to find the thread on the forum.
