On graphing calculator, enter your data and use stat plot to graph the points.  Then use your regression analysis to find the coefficients for each equation. 

a. the shape is of a cubic function, so using cubic regression: y = x^3 - 5x^2 + 10x - 11

b. The shape is of an exponential function, so using exponential regression: y = (5.517)(2.207)^x

c. The shape is of a quadratic function, so using quadratic regression: y = 66.286x^2 - 314.8x + 279.8

d.The shape is of an exponential function, so using exponential regression: y = (0.354)(2.518)^x

e. the shape is of a negative cubic function, so using cubic regression: y = -8x^3 + 8.857x^2  - 25.11
