Points are plotted for the years up to 2030. The points are the values of the function, X-formula, 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.
