First of all, there's a lot of correct answers.
00:03
So what i'm going to do is just give you the answer that is the easiest for me.
00:08
I'm seeing that it goes up to 1, 1, hits down here at 4, negative 5, and then goes back up to the top at 7, 1.
00:24
And so what i'm going to do is make this a cosine curve because i'm choosing to start at a maximum.
00:33
The next thing that i'm going to point out is the length of the period is going to be equal to 7 minus 1.
00:41
It's when we repeat those maxes.
00:43
So that's 6.
00:44
And when i go to my equation, because that's my ultimate goal, that b value that's in the equation will be 2 pi divided by that 6, which would give me pi over 3 when i reduce.
00:55
The next thing i'm going to do is the midline, which is going to be y equals.
01:01
What i like to do is add the max value with the min value and then divide by 2.
01:08
So that's looking at negative 4 divided by 2, which is negative 2.
01:12
And then the last thing, i'll just write this in green because i've run out of colors, is the amplitude...
