Question

Use a graphing calculator to write a polynomial function to model the data.

 

Row 1...x,-2.5,-2,-1.5,-1,0.5,1,1.5,2

Row 2...f(x) -2.4,-5,13,7,-3,2,15,29,48,86

Answer 1

When all else fails, follow directions!

The data should be plotted, and an appropriate regression (curve fit) can be performed, after you decide the right kind by viewing the shape of the graph.

It is assumed that you have been trained on doing regressions with a graphing calculator.
