The table to the right shows estimates of mobile data traffic, in exabytes (1018 bytes) per month, for years from 2015 to 2020. (A) Let x represent the number of years since 2015 and find an exponential regression model (y=abx) for mobile data traffic. (B) Use the model to estimate the mobile data traffic in 2028. (A) Write the regression equation in the form y = ab*. y=0.0* (Round to four decimal places as needed.) Mobile Data Traffic (exabytes per month) Traffic 3.5 6.1 9.3 15.1 22.2 28.4 Year 2015 2016 2017 2018 2019 2020
