The approximate rate of change in the number (in billions) of monthly text messages is given by the equation: f'(t) = 7.5t - 16.9, where t represents the number of years since 2000. In 2005 (t = 5), there were approximately 9.2 billion monthly text messages. Complete parts a. and b. below. a. Find the function that gives the total number (in billions) of monthly text messages in year t. b. According to this function, how many monthly text messages were there in 2009?
