Question

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

Answer 1

For this case we have an equation of the form:
 $y = A * (b) ^ x$
 Where,
 A: it is the initial amount
 b: is the rate of change
 x: it's time
 We then have the following equation:
 $y = 12000 * (0.8) ^ x$
 According to the previously explained, the current population is:
 $A = 12000$
 Answer:
 the current population of elk at the park is:
 $A = 12000$
