Question

For the model y = 150(0.8)^x in the problem, what will be the world population of Iberian lynx in 2020? Year Population2003 1502004 120 A.2B.3C.20D.39

Answer 1

B

1) In this question, y stands for population, and x stands for year.

2) Since the first year is 2003, then 2020 -2003 = 17. Let's plug into x, this value:

`\begin{gathered} y=150(0.8)^(17) \\ y=3.37\text{ } \\ y\approx3 \end{gathered}`

3) Rounding off to the nearest whole number, the population of Iberian lynx will be approximately 3 lynxes.
