Answer:
Exponential decay
Step-by-step explanation:
Hi there!
We know that this is an exponential function because x is an exponent.
Because the base of the power is 1/2, it is an exponential decay. Whenever the growth/decay factor is less than 1 but greater than 0, it makes the function an exponential decay.
I hope this helps!
