Final answer:
The maximum value of a standard sine or cosine function is 1, which corresponds to the amplitude of these functions. Without specific details of the function in question, it is not possible to provide an accurate answer.
Step-by-step explanation:
When examining the question about the maximum value of a function, it is not entirely clear which function the question refers to, as the specifics of the function are missing. For any periodic function like a sinusoidal wave (which is a common context in physics problems), the maximum value (also known as the amplitude) is the greatest distance the function reaches from its mean value. When assessing a sine or cosine function, this maximum is typically indicated by the coefficient in front of the sine or cosine term. If by chance the function implied was y = sin(x) or y = cos(x), then the maximum value is 1, because these functions oscillate between -1 and 1. Without additional information, we can't accurately determine the maximum of the function being asked about.
