Graph titled M Stock. The x axis is labeled time, in weeks, and ranges from 0 to 14 in increments of 2. The y axis is labeled price per share, in dollars, and ranges from 0 to 70 in increments of 10. Point P is plotted at 0, 40, and the graph goes down to point Q at 3, 20. Then the graph goes up to point R at 8, 35; down to point S at a little more than 11, midway between 25 and 30. Finally the graph goes up to point T at a little less than 14, 60.

The functions h of d, g of y, and f of m each represent the balance of a savings account that is opened with an initial balance of a dollars, with no additional deposits of withdrawals.

  • f of m equals a open parentheses one point zero zero zero eight raised to the power of m close parentheses where m is the number of months since the account was opened
  • g of y equals a open parentheses one point zero one raised to the power of y close parentheses where y is the number of years since the account was opened
  • h of d equals a open parentheses one point zero zero zero zero five raised to the power of d close parentheses where d is the number of days since the account was opened

If the time period is the same for all three accounts, order the functions from greatest to least growth rate.

Drag and drop the functions into the correct order.
