Question

The (period,amplitude,frequence) of y=1/4cos1/2x is 4pie.

one of these is the answer need help

Answer 1

period

Explanation:

The attached graph shows a period of the function. Its amplitude is 1/4 (vertical distance from centerline to peak). Its period is 4π (horizontal distance from peak to peak). Its frequency is the reciprocal of the period, so would be 1/(4π).

The value 4π is the period of the function.
