Answer all parts please.

Total personal income of the country (in billions of dollars) for selected years from 1955 to 2000 is given in the table (a) These data can be modeled by an exponential function. Write the equation of this function, with x as the number of years after 1955 (b) if this model is accurate, what will be the country's total personal income in 2005? (c) in what year does the model predict the total personal income will reach $22 trillion? Year 1955 1965 1975 1985 1995 2000 Personal Income 4066 8324 23063 48854 84255 10.2338 (a) The equation of an exponential function that models the data is y-O (Use integers or decimals for any numbers in the expression Round to three decimal places as needed)
