Answer:
A. Periodic; About 6
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.
