3.Plot the level of real GDP (FRED code: GDPC1). Then, plot the rate of economic growth as the percent change from a year ago of this index. Describe how real GDP behaves in recessions, which are denoted in the FRED graph by vertical shaded bars. If you registered on FRED (as in Data Exploration Problem 1), save the graph so that you can recall and update it easily when new observations become available. (With Upload a graph )

4.Examine nominal GDP (FRED code: GDP) based on a figure showing percent change from a year ago. What was special about the behavior of nominal GDP during the financial crisis of 20072009 compared to previous decades? (With Upload a graph)

5.Plot on one figure the percent change from a year ago of both the GDP deflator (FRED code: GDPDEF) and real GDP (FRED code: GDPC1). How does the GDP deflator link nominal and real GDP? Since the mid-1980s, does it fluctuate more or less than real GDP? (With Upload a graph)
