Question

What is the quadratic regression equation that fits these data?

Answer 1

Answer:

the answer is a.

Step-by-step explanation:

I plugged your data into a graphing calculator, and got a quad reg in the picture.

Answer 2

Answer:

Option: A is the correct answer.

The quadratic equation that fits these data is:

            A.   $y=2.09x^2+0.33x+3.06$

Step-by-step explanation:

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.   $y=2.09x^2+0.33x+3.06$
