Graph Gallery Mission impossible Investigation

This spreadsheet generates random cubic functions. It shows three views of each randomly generated function. Your task - if you should choose to accept it - is to find out, by analysing the graphs,what the range of each coefficient in the cubic function is.

Once you know the range of each coefficient you can use it to construct the password you need to unlock the spreadsheet. Then enter the correct theoretical probabilities and compare them to the experimental probabilities.

Good luck.
