Answer:
and 
Step-by-step explanation:
The equation of the isotope decay is:
14-Carbon has a half-life of 5568 years, the time constant of the isotope is:
The decay time is:
(There is no a year 0 in chronology).
Lastly, the relative amount is estimated by direct substitution:
1- y= x/2 + 2
2- y= 3x +1
3- y= x/2 - 2
4- y= 3x - 1
