So the range, what that range means is what values of y, what values of y, which means how far up, how far up, how far up, and how far down? does my graph go? all right, how far up and how far down does it go? that's going to be the range, right? what is my y? what values can my y take and the y is up and down? okay, so that being said, let's look at our picture right.
00:36
Of course the y like i said is up and down.
00:39
So we're saying what values of this graph are up, right? well, that's as high as it goes, right? and that's going to be looks like an eight.
00:47
It's going to be two under that ten.
00:49
So the highest that are ys can be looks like is eight.
00:54
All right.
00:54
So now let's look how low does it go? how low does it go? all right? so let's see.
01:00
We have that's as low as it can go right there.
01:02
And that looks like it's down one up from negative 10...
