Question

Select the regression equation that best fits the following data

Answer 1

.Plot the points (x, f(x)) given by the table and the given functions.

Of all the given functions, the only one that models all the plotted points closely is the red curve.

The function that is given by the red curve is:

`f\left(x\right)=-21.30x^(2)+231.22x+318.41`

Therefore, the regression equation that best fits the given data is f(x) = -21.30x² + 231.22x + 318.41
