Answer:
The term that describes how long it takes a function to repeat its behavior is the:
PERIOD.
Step-by-step explanation:
A function f is said to be periodic if, for some nonzero constant P, it is the case that
for all values of x in the domain. A nonzero constant P for which this is the case is called a period of the function.
i.e. it is the smallest number such that after which the function repeat itself.
Hence, the answer to the given question is:
Period.
