If f(x) = x^3/(x^2-4), find f(x + 2)?

Question

If f(x) = x^3/(x^2-4), find f(x + 2)?

Answer 1

I realize you are trying to solve a problem and find f(x+2).  That is either the strangest last name I have ever seen or you are posting in the wrong place.

Answer 2

If the question is going to assist me in finding dead relatives...

I'll try to solve it.  Otherwise, please post in a mathematics forum.

Answer 3

(x+2)^2/x

Answer 4

You might get a better response over in the mathematics forum,

Why did you post it in the genealogy forum, ?

Answer 5

Just substitute x + 2 for x

f(x + 2) = (x + 2)^3/((x + 2)^2 - 4)

f(x + 2) = (x^3 + 6x^2 + 12x + 8)/(x^2 + 4x + 4 - 4)

Simplify

x^3 + 6x^2 + 12x + 8

---------------------------- This is the final answer.

..........x(x + 4)

Edit:

By the way, what does this have to do with Genealogy?
