f(x)+f(y) for all values of x and y. Which of the

following statements must be true when a=b?

I. f(a+b)=2f(a).

II. f(a+b)=[f(a] to the power of 2.

III. f(b) +f(b)=f(2a)

The problem ask to choose among the following statement that tells the truth about the said function f and the best answer among the following statement is in statement I. f(a+b)=2f(a) and statement III. f(b)+f(b) = f(2a). I hope you are satisfied with my answer and feel free to ask for more
