    Step-by-step explanation:

    The number of web searches S (x) in billions on a particular web during year x can be approximated by

    S (x) = 227x - 454,921 ... (1) from 2009 to 2012

    Therefore, S (2011) = 227 * 2011 - 454921 = 456497 - 454921 = 1576 Billions.

    That means in the year 2011, the number of web searches on that particular web can be approximated as 1576 billion. (Answer)
