Answer:
The exponential regression equation is [tex]y=99.06\cdot 0.68^{x}[/tex]
Option 4 is correct.
Step-by-step explanation:
We are given a table of x and y of a data set.
We need to model exponential regression equation of given data set.
Using expRegression calculator.
We will put the table value into calculator and find the equation of x and y
Exponential Equation: [tex]y=ab^x[/tex]
We get the equation using calculator
[tex]y=99.06\cdot 0.68^{x}[/tex]
where, 99.06 is initial value of the regression
and 0.68 is rate factor of exponential regression.
Hence, The exponential regression equation is [tex]y=99.06\cdot 0.68^{x}[/tex]
