While the mathematical part of this task is suitable for assessment, the context makes it more appropriate for instructional purposes.

Carbon 14 is a form of carbon which decays exponentially over time.

The amount of Carbon 14 contained in a preserved plant is modeled by the equation  f(t) = 10\left(\frac\right)^.

What methods do they use and how do these methods work?

In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.

­ ­You probably have seen or read news stories about fascinating ancient artifacts.

At an ar­chaeological dig, a piece of wooden tool is unearthed and the archaeologist finds it to be 5,000 years old.

Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.

It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.

Creationists often criticize radiocarbon dating in the context of discussions of the age of the earth.
