Homework Statement


Determine the inverse of the exponential regression equation that you foun in the first bullet.


Homework Equations



y=ab^x

The Attempt at a Solution



  • in the first bullet i got the equation

y= (8.7166)(0.93240)^x

  • then i found using logs that x = -5

so the exponential regresion inverse

would be

x= (8.7166)(0.93240)^y
  • this wil become
log(0.9324)^(x / 8.7166)=y

  • so would that be the answerd ..or would i have to replace the x for the -5 and then solve for y
  • and isolate x to leave the formula as x=ab^y were i have all the values for a b and y ....??

thank in advance for your help and time reading my Thread .
