Question

which term gives the number of cycles of a periodic function that occur in one horizontal unit?
○ vertical shift
○ period
○ frequency
○ phase shift

Explanation:

• Vertical shift refers to the vertical movement of a function, not related to cycles per unit.
• Period is the length of one cycle, not the number of cycles per unit.
• Frequency is defined as the number of cycles of a periodic function in one horizontal unit, which matches the question.
• Phase shift is the horizontal shift of a function, not about cycles per unit.

Answer:

C. frequency
