00:01
So, in this problem from the given graph, we can point out certain information.
00:10
So, in part number one, we can see that the midline of the function, midline of the function is y is equal to one which is obtained from the graph and this is one of the answers for the first part of the problem and the amplitude can be observed as four.
00:31
Why? because that is the maximum displacement of the graph along the y -axis.
00:39
So, that is the amplitude.
00:41
So, we go to question number two.
00:43
Here we have to find the period.
00:45
So, period, what do we mean by period? that is the time taken to complete one oscillation that is taken to reach the starting point after beginning the course of the journey.
01:03
Therefore, in this graph, the period of the function is pi because after pi interval, the point on the graph again reaches to the same point...
