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) 180 90 45
Which exponential function best represents the relationship between f(t) and t?
f(t) = 0.5(180)t
f(t) = 180(0.25)t
f(t) = 180(0.5)t
f(t) = 0.5(50)t
