Determine whether the function is periodic. if it is, find the period.
a. periodic; about 6

b. periodic; about 3

c. periodic; about 12

d. not periodic

A. Periodic; About 6

Step-by-step explanation:

We know that,

A periodic function is a function which repeats its values in regular intervals.

From the graph, we see that,

The function starting from the point x= -3.5 repeats itself from the point x= 2.5

Thus, the function is a periodic function.

We know,

Period is the non-zero real number after which the function repeats itself.

So, the period of the given function = 2.5 - (-3.5) = 2.5 + 3.5 = 6

Thus, period of the given function is 6.

Hence, option A is correct.
