Here we're given the equation, or rather a graph of a function, and we want to identify the amplitude, period, and the midline.
00:06
What i like to do, even though it's list last always, i like to start with the midline because it's the easiest in my opinion.
00:13
And it's also one that you can often get wrong, but you can check yourself.
00:18
So i'm going to look at this and just say, well, what's the middle point? i think this is the very middle of the graph.
00:24
If you're wrong, don't worry about it too much, because the next step is to check that value.
00:30
So i'm going to say the mid value, i'm going to say k is 2.
00:33
That's the midpoint.
00:35
Now the next step is to find the amplitude.
00:38
The amplitude is the distance from the midline to the peak...
