Using a calculator, the quadratic regression equation that fits the data is:

C. y = 2.13x² + 0.13x + 6.39

How to find the equation of regression using a calculator?

To find the equation, we need to insert the points (x,y) in the calculator.

In this problem, the points are:

(-4,40), (-3,28), (-2, 10), (-1, 8), (0,7), (1,10), (2,16), (3,26), (4,40).

Hence the equation is:

C. y = 2.13x² + 0.13x + 6.39
