Answer:
In exponential growth, the rate of growth is proportional to the quantity present. In other words, y′=ky. Systems that exhibit exponential growth have a constant doubling time, which is given by (ln2)/k. ... Systems that exhibit exponential decay have a constant half-life, which is given by (ln2)/k.

Exponential decay is the correct answer.
