A company collected data for the number of text messages sent and received using a text-message application since October 2011. The table shows the number of text messages sent and received in billions over time. The data can be modeled by a quadratic function. Text Messages Number of Months since October 2011, t Number of Text Messages, n(t) (billions) 3 10 10 15 17 20 27 25 44 30 64 35 86 40 112 Vhich function best models the data? An(t) = -0.002t² + 0.55t + 5.02 n(t) = 0.072t² - 0.15t + 2.73 n(t) = -0.002t² + 5.02 %D
