Homework Help: algebra

Posted by lee on Tuesday, January 8, 2013 at 10:26am.

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 quadratic model for the data. Use the regression feature on your calculator to find each model. Which model is a better fit? Explain.

weight(in grams)
140 150 170 175 205

weight (in inches)
1.4 1.25 0.93 0.78 0.43

Can someone please help me with this problem I'm totally lost.
