Question

The function f(x)=1200(0.8)^x represent the possible elk population of a national park x years from now. What is the current population of elk at the park? A.960 B.1200 C.1500 D.768

Answer 1

If x is the number of years from now, that means the current population is when x=0

Therefore, we plug this into the equation:

f(x) = 1200(0.8)^0 = 1200 elk at the park currently

Answer 2

Answer:

B.1200

Step-by-step explanation:

This equation is in the form

$y=a\times b^x$

where a represents the initial value and b represents 1 plus the growth rate as a decimal number.  In this equation, the number in place of a is 1200; this means the initial value, or current population, is 1200.
