<p>Hi all.</p>
<p>I'm sorry I can't provide the specific context for my problem; it was a practice free response that I turned in. Basically, the problem asked for a "formula" that satisfied a specific condition. I came up with a recursive function, something along the lines of...</p>
<p>Valid where n is such that n > 0, f(n) = x^n * f(n-1)</p>
<p>Is this a valid answer? Will collegeboard accept a recursive function like that?</p>
<p>Thanks for any input.</p>
