Many people in the recording industry have been impressed by the success of Apple's iTunes Music Store. The polynomial 0.32x2 - 0.36x + 0.21 approximates the number of song downloads from iTunes. When x = 0, the polynomial estimates the number of downloads (in billions) as of January 2004. when x = 1, it estimates the number of downloads (in billions) as of January 2005, and so on. Suppose the trend continues. Use the polynomial to estimate the number of iTunes downloads as of January 2013.t (Round your answer to one decimal place.) 18 x billion downloads
