The amount of a radioactive material changes with time. The table below shows the amount of radioactive material f(t) left after time t: t(hours) 0 1 2 f(t) 100 50 25 Which exponential function best represents the relationship between f(t) and t? (1 point) f(t) = 0.5(100)t f(t) = 100 (0.25)t
f(t) = 0.25(50)t
f(t) = 100(0.5)t
