La expresión correcta que da la población de la especie t años después de que comenzó, suponiendo que la población está viviendo en condiciones ideales, es:<br /><br />$100\times 2^{\frac {t}{9}}$<br /><br />Esta expresión se basa en el hecho de que la población se duplica cada 9 años, lo que se puede modelar con una función exponencial donde la base es 2 (duplicación) y el exponente es t/9 (doble cada 9 años).
