Find f(2) of a Polynomial Function | R and f(2)=5

[Dick]

I do not know how to derive a but assuming a=1, I can find k.

You would able to derive it if you used some other properties of f(x) you figured out before.

In your post 27 you wrote, correctly,

g(x)g(y)=g(xy)

Substitute g(x) = ax^k in there.

Thanks!

PS-This was the longest thread I have ever started.
