What is Carbon 14 Dating? What is it used for?
Carbon-14 dating is process of determining the age of archaeological artifacts.
Up to roughly 50,000 years old, some biologically derived archaeological artifacts (such as remnants of plants, fiber, wood, or bone) can be aged using carbon-14 dating.
A fossil is 11460 years old if it contains, say, 25% more carbon-14 than the living sample (because it contains one-fourth as much carbon, it is 5730*2=11460 years old).

The technique of carbon-14 dating, also referred to as radiocarbon dating, is based on measuring the rate at which carbon-14, a radioactive isotope of carbon, decays within a sample. Carbon-14 is continuously produced in the atmosphere and is absorbed by living things through photosynthesis or consumption of other organisms; after an organism dies, it stops absorbing carbon-14, and the remaining carbon-14 starts to decay at a known rate. Scientists can determine the age of a sample by measuring its remaining carbon-14 content and comparing it to the initial amount found in the atmosphere. Carbon-14 dating is frequently employed in geology, archaeology

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
