The function f(x)=12000(0.8)/\xrepresents the possible elk population of a national park x years form now. what is the current population of elk at the park

For this case we have an equation of the form:
 
 Where,
 A: it is the initial amount
 b: is the rate of change
 x: it's time
 We then have the following equation:
 
 According to the previously explained, the current population is:
 
 
 the current population of elk at the park is:
 

1.3 and 1 1/3 are both closest to 1. hope this ; )
