Which one???? PLEASE

Answer:
Step-by-step explanation:
Sofia, since we don't have access to the previous slide, as it says in the directions, we can't really know.
But, I do know that decay is almost always modeled as
[tex]e^{-something}[/tex] which would be an exponential function but.. this also depends on when you want to check, b/c maybe for a short period of time it would look linear.. sooo look at the pervious slide to see the time frame they are asking about
