Question

Determine whether the function is periodic. If it is, find period.

A. periodic; about 1.5

B. periodic; about 2

C. Not periodic.

D. Periodic; about 3

Answer 1

I do not think there is a period due to how uneven the amplitudes are.

Hope this helps. (:

Answer 2

The correct option is C.

Explanation:

A function is called periodic function if it repeats the values in regular intervals or periods.

From the given graph it is clear that the function is not repainting its values from -6 to 6. It means the function is not periodic.

From the given graph it is also noticed that the amplitudes of the functions are not same, therefore the function is not periodic.

Therefore correct option is C.
