Question

The following table represents amount of vanadium-49 remaining in a sample of rock

day grams of vanadium-49
0 100
330 50
660 25
990 12.5

which type of function best models the given data?

Answer 1

This is an example of an exponential decay problem.

The basic format of the equation is:
`y=ab x^(123) x`

In this problem, the starting amount is 100. The rate is 0.5 because it is being cut in half every 330 days.

Answer 2

exoponential decay function
