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? (1 point) f(t) = 0.5(180)t f(t) = 180(0.25)t f(t) = 180(0.5)t f(t) = 0.5(50)t

Answer :

f(t)=(0.5)^t *180 is the answer because (0.5)^0=1   (0.5)^1=0.5   (0.5)^2=0.25
