Question

The function y = 60x 1+0.625x models the moose population in a small New Hampshire forest over a period of time. What is a reasonable domain for this function?
A)0 < x < ∞
B)−1.6 < x < ∞
C)−∞ < x < ∞
D)−∞ < x < −1.6

Answer 1

I think that the correct function in your question should be y = 60x⁻¹ + 0.625x.

With that said, the answer is A. 0 < x < ∞
By the process of trial and error of the choices, we can see that this choice satisfies the equation. Take note that y models moose population, so y should always be positive.
