this table shows the profit for a company (in millions of dollars) in different years.

the quadratic regression equation that models these data is y = - 0.34x^2 + 4.43x + 3.46. using the quadratic regression equation, what was the predicted profit in year 8?

$17.14

Step-by-step explanation:

Given :

To Find : Using the quadratic regression equation, what was the predicted profit in year 8

Solution :

Where y is profit and x is year

Substitute x = 8

So, Option D is true

Hence the predicted profit in year 8 is $17.14

Predicted profit in year 8 is 17.14 millions of dollars.

Step-by-step explanation:

The quadratic equation

predicts the profit y for a company in year x.

The profit in year 8 is the value of y at x=8:

Hence, predicted profit in year 8 is 17.14 millions of dollars.
