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

Answer 1

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.

Answer 2

The number 1.6 is the percent increase every year.

The population increases 1.6 times Per year
