Question

Suppose the exponential regression equation for some data is y=3.959*8.115^x. When x equals 3, what is the predicted value of y? Round your answer to the nearest whole number.

Answer 1

y = 3.959*8.115^3 = 2116 to nearest whole number .

Answer 2

The predicted value of y is 2116.

Explanation:

Here, the given exponential regression equation,

`y=3.959(8.115)^x-----(1)`

When,

`x=3`,

From equation (1),

`y=3.959(8.115)^3`

`=2115.68532774`

`\approx 2116`

Hence, the predicted value of y, when x is 3, is approximately 2116.
