What is the quadratic regression equation that fits these data?

Option: A is the correct answer.

The quadratic equation that fits these data is:

            A.  

We are given a table of values as:

    x          y

    -4        35

    -3        20

    -2         12

    -1           6

    0           2

     1           6

     2          10

     3          24

     4          38

From the given data values we see that the points follow a parabolic path this means that the line of best fit will has a quadratic equation.

Also, the line that best represents these data points as is done by the regression calculator is:

                A.  

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.
