Question 1128845
<br>
(I) The growth factor is the ratio of any two successive measurements.<br>
{{{0.1/0.6 = 1/6}}}<br>
The growth factor is 1/6.<br>
(II) The value changes from 1 to 1/6, a decrease of 5/6.  The fractional change is -5/6; the percent change is - 83 1/3%.<br>
(III) Given: the initial value (when x=0) is 21.6.<br>
(IV) F(x) = 21.6(1/6)^x<br>
Note: Use the fractional form of the growth factor because it is exact; a decimal would only be an approximation.
