Question

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?

f(t) = 0.5(100)t

f(t) = 100 (0.25)t

f(t) = 0.25(50)t

f(t) = 100(0.5)t

Answer 2

i dont think that your graph is correctly stated

Answer 3

yeah something isn't adding up right

Answer 4
