Question

The function f(x) = 40(0.9)^x represents the deer population in a forest x years after it was first studied. What was the deer population when it was first studied?a. 44b.40c. 36d.49

Answer 1

We are given the function that models a deer population:

`f(x)=40(0.9)^x`

Where x is the years since the study started. If we want to know the initial population, we want to find the population at x = 0 years.

Thus:

`f(0)=40(0.9)^0=40\cdot1=40`

The correct answer is option b. 40
