Points are plotted for the years up to 2030. The points are the values of the function, Xformula, evaluated at the years in the year column. The function can be evaluated at the years for which pop is missing: 2010, 2020, and 2030. The smoother that is shown is only an approximation to the function. You want to see the function itself.
