What is an example of an exponential decay

One example of exponential decay is the amplitude of an unpowered pendulum.

Step-by-step explanation:

Exponential decay is when something gets smaller and smaller at a nonlinear rate. When a pendulum swings it could start with a large swing but as it slows down it will slow down more and more each time until eventually it stops.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

your answer would be 12
