Here is the Etsy annual profit in millions of dollars for the years $2012-2022.$ I've scaled the years to be years since $2010.$

$\backslash$table$[[$Year$,$Net Income $($$mm$)],[2,-3],[3,-1],[4,-15],[5,-54],[6,-30],[7,82],[8,77],[9,96],[10,349],[11,493],[12,-694]]$

A$.$ Create a scatterplot for the data in Excel or Googlesheets.

B$.$ Determine the cubic model for the data. State the equation and the $R^2$ value. $(R^2$ is a statistical measure on how well the equation fits the data. The closer the $R^2$ value is to $1,$ the better the fit. Anything over $0\mathrm{.}8$ is typically a 'good' fit.$)$

C$.$ Now determine a new model if you exclude the year $2022.$

C$.$ Now determine a new model if you exclude the year $2022.$

Use your model from part $C$ to determine the Marginal Profit in $2017.$

E$.$ Use your model from part $C$ to determine the inflection point for the Profit.

$10.$ Here is Etsy's annual Revenue from $2012-2022$ in billions of dollars. Again, I've scaled the years.
