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, M

, 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 T

years since the initial measurement.
