17. The function f(x) = - 5x ^ 2 + 17x + 21 models the predicted sales of a pen after price increases . Use the table showing actual and predicted sales to find the residuals for the model.
X. - Actual Sales. - Predicted sales - residuals
0 - 22 - 21
1 - 33 - 33
2 - 36 - 35
3 - 28 - 27
18. Function g also models the data in Question 17. For function g, the average distance of the residuals from the line y = 0 is 1.1 . Is f or g a better model for the data?
