Which quadratic regression equation best fits the data set?

x y
0 31
1 29
2 28
4 22
6 19
10 11
11 8

answers:

yˆ=31.179x^2+2.051x−0.002

yˆ=−0.002x^2−2.051x−31.179

yˆ=−0.002x^2−2.051x+31.179

yˆ=31.179x^2−2.051x−0.002

The third equation is correct. The easiest way to solve a problem like this is to plug the x-values from the chart into the equations and see which one equals the y-value in the chart.
