B) the horizontal length of one cycle of the function

C) the number of cycles of the function that occur in one horizontal unit

D) a vertical translation of the function

The right answer for the question that is being asked and shown above is that: "C) the number of cycles of the function that occur in one horizontal unit." the phase shift of a periodic function is that C) the number of cycles of the function that occur in one horizontal unit
