Consider the tables created using an initial investment of $1,000 and quarterly compounding of interest. Table A represents the function that models the total amount of one investment, a(x), based on the annual interest rate, x, as a percent.

Table B represents the function that models the interest rate, r(d), as a percent, based on the total amount at the end of the investment, d.

Use the values in the table to verify the relationship between the functions representing the investments. Which conclusion can be made?
