content area bottom Part 1 (a) Find an exponential model of the form f(t)equalsy Subscript 0b Superscript t for these data, where t equals 0 corresponds to the year 2000. If you do not have suitable technology, use the first and last data points to find a function. If you have a graphing calculator or other suitable technology, use exponential regression to find a function. The exponential model for the data is f(t)equalsnothing left parenthesis nothing right parenthesis Superscript t . (Round to three decimal places as needed.) Part 2 (b) Assume that the model remains accurate, and predict the total assets in 2018 and 2021. The total assets in 2018 will be enter your response here trillion. (Round to one decimal place as needed.) Part 3 The total assets in 2021 will be enter your response here trillion. (Round to one decimal place as needed.) Part 4 (c) Use a graphing calculator (or trial and error) to determine the first full year in which the total assets exceed 450 trillion. The first full year in which the total assets exceed 450 trillion is enter your response here
