Answer:

Option: A is the correct answer.

The quadratic equation that fits these data is:

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

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
