No one is right
Explanation:
John Case:
The function is defined between -1 and 1, So it is not possible obtain a value greater.
In addition, if you move the function cosine a T Value, and T is the Period, the function take the same value due to the cosine is a periodic function.
Larry case:
Is you have , the domain of this is [0,2].
it is equivalent to adding 1 to the domain of the , and its mean that the function , in general, is not greater than .
