Part A
The function (X) = -4X2 + 18x + 16 models the predicted sales of a hat after x price increases. Use the table showing actual and predicted sales
to find the residuals for the model
Drag the numbers to complete the table. Numbers may be used once, more than once, or not at all.

Part B
Function g also models the predicted sales of the hat in Part A. For function g, the average distance of the residuals from the line y = 0 is 1.3. Is f
or g a better model for the data?
