Question

The function f(x) = 58(1.6)x represents the possible bird population in a park x years from now. Each year, the expected number of birds is ____ the number the year before.

A. 6 more than
B. 0.6 times
C. 6 times
D. 1.6 times

Answer 1

It would be 1.6 times so it would be D

Answer 2

Option D 1.6 times

Explanation:

The function f(x) = 58(1.6)x represents the possible bird population in a park x years from now.

Each year the expected number of birds will be 1.6 times the number the year before.

Since in the function f(x), x is the number of years and 58 is the initial population in the park.

Therefore,(1.6) is the factor by which population of birds will be increasing.

Option D 1.6 times is the answer.
