Question Help 7.6.31 A survey approximates the number of Americans that are age 65 and older and projects that by the year 2050, approximately 82.3 million Americans will be at least 65 The bar graph shows the estimated number of Americans with projected figures for the year 2020 and beyond A graphing cakculator screen displays an exponential function that models the U.S population age 65 and over, y, in millions, x years after 1899. Use this information to solve (a)H(d) below ExpReg Click the icon to view the bar graph a 3443104327 b 1.023145946 A An exponential function was used because the data in the bar graph is increasing more and more rapidy. XB. An exponential function was used because there are too many data points to use a linear function n exponental function was used because population is always modeled using exponential functions D An exponential function was used because exponentsial functions are always more accurate than linear functions An exponential function was used because always mor b. Use the graphing calculator screen to express the model in function notation, with numbers rounded to three decimal places Enter your answer in the answer box and then click Check Answer parts emaining Clear Al Final rch
