Answer:
The quadratic regression equation for the given data set is:
Option: C
[tex]C.\ -0.875x^2-3.5964x+20.179[/tex].
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:
[tex]-0.875x^2-3.5964x+20.179[/tex].
