It looks like you kind of understand the x values being the domain and having to combine them together.
00:05
Because as you look at the problem from here to here, and then even though there's a jump in the graph, every x value is defined along that curve going up here, and then you even have an open and then going down, just double checking that that one is also open.
00:24
So what i care about is that every value is defined and all the way to the left is negative five and all the way to the right is positive four, which might be why you have some comments on there that the domain is going to be from negative five with a bracket all the way to four with a parenthesis.
00:44
And just to, i guess, further clarify, the bracket is closed, whereas the parenthesis is open.
00:53
If i do the same thing for the range, it's not as easy because you have this blank space.
00:59
Let me just circle it.
01:01
There's no y values being hit in here, but now you're looking at how low the graph goes, which it looks like it's as low as negative five, but that's an open.
01:13
So i'm going to go from negative five.
01:16
And even though there's an open here, there's a defined value on this side where it's closed...
