We want to find the equation of the provided graph, and the first thing i'm going to do is i'm going to identify the midline.
00:10
Now, the midline is the middle line.
00:12
So the highest point is 2, and the lowest point is negative 4.
00:17
The number in the middle will be that negative 1.
00:22
So that line there is the midline, and it goes through negative 1.
00:31
Therefore this here is negative one.
00:36
Now, the height of this graph from the midline, if i go straight up to the maximum, i can see that that's one, two, three, and then if i go from the midline down to the minimum, i can see that that's also three.
00:56
Now, this box here is going to be three.
01:01
But because the graph, when you look at the y intercept here, the y intercept is below the midline, for that reason, the 3 is going to be a negative.

Now, the period...
