How Do I do this on my calculator? im so confused.. Archers need to use arrows that do not bend easily. The table shows how the weight of an arrow affects 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 find a linear and a quadratic model for the data. Which model is a better fit? Weight in grams: 140 , 150, 170, 175, 205
weight inches: 1.4 , 1.25, 0.93,0.78,0.43
