regressions(different models)

Question

year amount (A)

2003 13.15

2004 14.91

2005 16.47

2006 17.41

2007 19.03

2008 18.79

(a) Use the regression feature of a graphing utility to find a linear model, an exponential model, and a logarithmic model for the data. Let t represent the year, with t = 3

corresponding to 2003. (Round all numerical values to to four decimal places.)

linear model: A=_____??

r^2= ____??

exponential model : A=___??

r^2=____??

logarithmic model: A=___??

r^2=______???

thanks youuu!

Answer 1

linear model: A=__1.1857

r^2= _0.9416

exponential model : A=_11.0073

r^2=___0.9294

logarithmic model: A=_6.4090

r^2=_0.9770
