Question

The function f(x) = 40(1.2)x represents the fox population of a forest x years after it was first studied. What was the original population of the foxes?

Answer 1

The original population of the foxes is when the years, $x=0$

$f(0)=40 (1.2)^{0}$
$f(0)=40$

Hence, the original population of the fox is 40
