D. 17%

Explanation:

i took the test

Answer 2

Option D. 17%

Explanation:

we have

`f(x)=250,000(1.17)^(x)`

This is a exponential function of the form

`f(x)=a(b)^(x)`

where

a is the initial value

b is the base

In this problem

a=250,000 people

b=1.17

Remember that

b=1+r

so

1+r=1.17

r=1.17-1=0.17

Convert to percentage

0.17*100=17%
