Answer 2

Answer:

The quadratic regression equation for the given data set is:

Option: C

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

Step-by-step 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:

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