6. (a) Research the population data of a country of your choice at http://esa. un. org/ unpd/wpp/unpp/panel_population. htm. Be sure to use data that includes information from 1950 to 2100. Use a graphing utility to plot the data. Compute "right handed secants" to create a chart of AP/At vs. the number of years since 1950. Plot this data in Geogebra as well, using a horizontal axis scaled in the same manner as your first graph. Repeat for AP2/A2t. Print and include all three graphs. (b) List three characterists of your graph of AP/At vs. t, and explain what those characteristics tell you about the graph of P vs. t. (c) List three characteristics of your graph of AP2 /A't vs. t, and explain what those characteristics tell you about the graph of P vs. t
