t is the time elapsed since the concentration was the A_=, this is the initial concentration. For example, for A_0 = 250, k = -10 (it has to be negative because this is a decay function) and b = 24, the function will be: F(t) = 250 *  24 ^ (- 10 t) And so, given that t is the time, you have the relation that gives the value of the dependent variable as a function of the time t. If the unit is hours, you could make this table: time, t in hours             F(t) = 250 * 24 ^ ( -10t) 0                                   250 * 24 ^(0) = 250 0.01                              250 * 24 ^ (- 10 * 0.01) ≈ 0.73 0.1                                250 * 24 ^ (-10* 0.1) ≈ 0.042 1                                  250 * 24 ^ ( -10) ≈ 0.000000000000016
