The amplitude of a periodic function is 2.5 and its minimum value is 0. What is the maximum?
The amplitude of a periodic function is the difference between its maximum and minimum values, divided by 2. In this case, the amplitude is given as 2.5 and the minimum value is 0.
Therefore, the difference between the maximum and minimum values is 2.5 x 2 = 5.
Since the minimum value is 0, the maximum value is 0 + 5 = 5.
So, the maximum value of the periodic function is 5.
