All right, so with this problem, i'm just going to go piece by piece.
00:04
Now, to find the period, you want to go from the consecutive maxes.
00:10
Now, i'm kind of on the fence on how to write my first answer for the period, because they give you 3 .14.
00:18
But i think you can infer from the directions that that would be pi.
00:22
But i'll go ahead and just stick with that 3 .14.
00:25
The next one is the minimum, which is how low the graph goes.
00:29
Let's try to use it back to that.
00:32
And it's at 1 .57.
00:34
But what we care about is that it's going down to negative 2.
00:38
So the min is equal to negative 2.
00:41
Now, the max is how high the graph is.
00:46
And i already labeled those two points as at 4.
00:50
And again, we're always given the y value, the min or the max.
00:54
Now, the midline is halfway between those two.
00:57
So let me just draw this in here...
