total amount paid on interest. 2. The following data are expected to follow a quadratic relationship. X 0.1 10 100 1000 y 3.667 3.724 4.223 7.247 17.0200 (a) Investigate this expectation with an appropriate scatter chart and 2nd degree polynomial trendline fit. Show the trendline equation and R2 value on the graph. (b) A quadratic function will plot as a straight line on linear coordinates when the ratio y- y1 x- X1 is plotted against x. Taking the second data set (1, 3.724) for the x, and y, coordinates, make such a plot and obtain a linear trendline fit to the data. Show the trendline equation and R2 value on the graph. How does this result compare with that obtained using the 2nd degree polynomial fit for the original data set
