Annual sales of bottled water in a certain country in the period 2007–2014 could be approximated by R(t) = 0.07t2 − 0.26t + 8.8 billion gallons (0 ≤ t ≤ 7), where t is time in years since 2007. According to the model, were annual sales of bottled water accelerating or decelerating in 2011? acceleratingdecelerating How fast? billion gal/yr2
