Question

What is the exponential regression equation for this data set?

Answer 1

The exponential regression equation is
`y=99.06\cdot 0.68^(x)`

Option 4 is correct.

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:
`y=ab^x`

We get the equation using calculator

`y=99.06\cdot 0.68^(x)`

where, 99.06 is initial value of the regression

and 0.68 is rate factor of exponential regression.

Hence, The exponential regression equation is
`y=99.06\cdot 0.68^(x)`
