input the following data into your calculator and obtain the best fit power regression function for y in terms of x, for the data

x 1 2 3 4 6

y 18.0 14.3 12.5 11.3 10.0

choose the one option which most closely describes the power relationship between x and y indicated by the regression model.

1) y �‡ �ãx
2) y �‡ 1/x^2
3)y �‡ x^2
4)y �‡ 1 / �ãx
5) y �‡ x^3
