Question

Hello! i need help on this question and the (select) questions have the options of 1997 to 2006

Answer 1

To find the average rate of change, we use the following formula

`r=(f(b)-f(a))/(b-a)`

Where a = 1998, f(a) = 856, b = 2001, and f(b) = 1591.

`r=(1591-856)/(2001-1998)=(735)/(3)=245`

(a) The average rate of change between 1998 and 2001 is 245.

We use the same formula between 2002 and 2006, where a = 2002, f(a) = 1483, b = 2006, and f(b) = 745.

`r=(745-1483)/(2006-2002)=(-738)/(4)=-184.5`

(b) The average rate of change between 2002 and 2006 is -184.5.

(c) As you can observe, the population was increasing from 1997 to 2001.

(d) The population was decreasing from 2001 to 2006.
