Answer 2

The quadratic regression equation for the given data set is:

Option: C

`C.\ -0.875x^2-3.5964x+20.179`.

Explanation:

We are given the data set of values of the input value i.e. x and output value i.e. y in table form by:

Input (x) Output(y)

0 20

1 16

2 10

3 0

4 -7

5 -20

Now when we represent these data points on the scatter plot; we see that the quadratic equation that is obtained by plotting these points is:

`-0.875x^2-3.5964x+20.179`.
