Okay, for this question i'm supposed to determine a viewing window that will show me everything that i need to see on this graph.
00:09
There's going to be certain things that i'm looking for.
00:12
The fact that it's to the third power and a positive coefficient, i know it's going to go up on the right and down on the left.
00:23
I also know that negative 47 is my y -intercept, so it's going to have to go there below there for the y minimum.
00:38
So, here's what i'm going to try.
00:40
I'm going to try negative 10 to 10 on the x -axis, and i will try negative 60 to positive 60 on the y's.
00:55
So, let me get it in my calculator and put this window setting in, and let's see what it looks like.
01:11
Okay, i'm gonna pause it till i get this in here.
01:14
Okay, in this viewing rectangle, here's what it looks like.
01:19
I see a little bit of this, and then i see this.
01:24
Well, it's kind of going out a little bit.
01:27
Okay, so what do i need? well, i need that right there.
01:33
So, i'm going to that y minimum.
01:38
I'm going to go down quite a bit on it.
01:40
Let's go down to, um, let's go to my, let's go negative 200 because i like quite a bit.
01:53
So, let's keep negative 10 to 10 because i can see the two ends of it, and i said negative 200, and then 60 is fine.
02:03
So, i'm gonna go push window, go down to y minimum, and change that to negative 200...
