(adsbygoogle = window.adsbygoogle || []).push({}); Cubic Regression

1. The problem statement, all variables and given/known data

(I was given a graph to enter into my calculator):

Let x represent time(in years) since 1980, and let y represent the corresponding U.S production of limousines.Enter the data in a graphing utility and find a cubic regression equation for the data.

2. Relevant equations

Calculator steps

Stat ---> Calc --->CubicReg... now what

3. The attempt at a solution

I have found the Cubic Regression equation but have forgotten how to make the equation itself appear in the y equals screen so that I can see the graph. I need that to answer the next part of the question.

I believe it should look something like this, but I'm not sure exactly how:

CubicReg L1,Y1,L2

Any help is greatly appreciated!
