Constructing exponential models: half-life (4:18)
- Carbon-14 is an element which loses exactly half of its mass every 5730 years. The mass of a sample of carbon-14 can be modeled by a function
, which depends on its age,
(in years). We measure that the initial mass of a sample of carbon-14 is 741 grams. Write a function that models the mass of the carbon-14 sample remaining
years since the initial measurement.
