Answer:
1 represents the number of years passed.
step -by-step explanation:
The amount of a radioactive isotope decays in half every year. The amount of the isotope can be modeled by f(x) = 346 (1/2)x and f(1) = 173
Here 1 represents the number of years that passed.
So 1 represents the number of years.
