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!
