The Population Division of the Department of Economic and Social Affairs of the
United Nations periodically releases estimates of the current populations of all countries, and also projections of the population sizes in coming years. In 2017, they released the2017 Revision of World Population Prospects, which includes predictions of populations until the Year 2100.
Table 1 on page 1 in the document includes seven sets of data on current and projected future populations of the world and of six regions. For each of the seven data sets, state what type of equation could be used to model the corresponding data (for example, linear with a positive slope, linear with a negative slope, quadratic curving up, etc). Briefly explain your answers; there is no need to produce specific equations. It might help to use Python to graph the data for each region. Note that the years of the predictions are not equally spaced, so plotting graphs is a good idea.
