The dogs of M.Twain

Perform calculations with the spreadsheet. Enter in column A the number corresponding to the day (ie 0, 1, 2 etc.), in cell B2 write the number of dogs with the formula that you are getting. In cell C2 write the coordinates of the point which has abscissa equal to the number of days and ordinate the same as the number of dogs in this way (A2, B2). You'll see the corresponding point on the graph. Drag the formula with the mouse in rows below to calculate the number of dogs in a given day and do the same in column C, to see the trend of the graph.
