Where are you stuck? You've plugged the years, starting with "t = 0" for "2005", into your graphing calculator, done the exponential regression, and... then what?
Please be complete. Thank you!
Time / Energy / Percentage/increase
2005 157 2.3
2004 153 1.11
2003 152 -0.7
2002 153 4.1
2001 147 0
2000 144 2.1
1999 140 2.9
1998 139 11.4
1997 138 0
Time(years) energy percentage increase over the year.
1. Determine the exponential equation using the rate of increase that relates to t (in years).
