Answer:
T = 20
min = 1
max = 0
Step-by-step explanation:
In the first image, the period is calculated by measuring the distance on the x-axis that it takes for the function to complete a cycle.
The attached image shows a way to measure the period, marking the distance from x = 0 until the wave completes the rise and fall cycle at x = 20.
Therefore the period is 20.
In the second image it can be seen that the lowest peak of the function is y = 1. The function is never less than y = 1. Therefore, that value is the minimum.
In the third image it can be seen that the maximum value of the function is y = 0. Since it is the maximum value that reaches the top peak
