For which function F(a+b)= F(a) + F(b) for all positive numbers a and b?
A, F(x)=x^2
B, F(x)= x+1
C, F(x) = x^1/2
D, F(x) = 2/x
E, F(x)= -3x
A, F(x)=x^2
B, F(x)= x+1
C, F(x) = x^1/2
D, F(x) = 2/x
E, F(x)= -3x
This question is asked a fair bit.rover_libra wrote:For which function F(a+b)= F(a) + F(b) for all positive numbers a and b?
