## Homework Statement

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

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 ...??

hello one more thing ..
the next bullet ask me the following...

• state whether the exponential regression model or the geometric sequence model better describes the given scenario.(explain your reasoning)

what are thay asking me to do..could anyone refrace that i don't understant even wht it means...thanks..

this athachement are part of the 1st post... it shows other parts of the same question mentioned...
thanks..
