Archers need to use arrows that do not bend easily. Th e table shows how the weight of
an arrow aff ects its spine, or the distance the center of the arrow bends when a certain
constant weight is attached. Graph the data in the table to fi nd a linear and a quadratic
model for the data. Use the regression feature on your calculator to fi nd each model.
Which model is a better fi t? Explain.
