Do all algabraic recursive functions have an equivalent non-recursive closed form function?

36 Views Asked by At

Given that we have a recursive function defined as

$\begin{matrix} f_{0}=0 \\ f_{n}=f_{n-1}+1 \end{matrix}$

We can come up with a related non-recursive closed form function defined as

$g(x)=x$

Where for every value of $n$

$f_{n}=g(n)$

Do all recursive functions defined with

$\begin{matrix} f_{0}=\text{an integer} \\ f_{n}=\text{an algebraic function(1)} \end{matrix}$

(1): where said function involves only algebraic operations, like, addition, subtraction, multiplication, and division, as well as fractional or rational exponents

have such a related non-recursive closed form function $g(x)$?

I'm not looking for how to find $g(x)$ if it exists, I`m just wondering if one always exists.
