Answer:

  • f(t) = 3^(t - 1)

Step-by-step explanation:

  • one dollar of the first day  = 3^0
  • three dollars on the second day = 3^1
  • nine dollars on the third day  = 3^2
  • twenty-seven dollars on the fourth day = 3^3

Numbers increase 3 times a day, it is an exponential function, powers of 3

The function is going to be:

  • f(t) = 3^(t - 1)

Options are not clear, it seems to be D
