So i believe you want to know what these notations mean.
00:03
So the first one you have this and that means the set of all points that are from negative to inclusive all the way up to 11 but not including 11.
00:17
And for your next part you have something of negative 2 to 11.
00:23
Now typically this would be written in interval notation like so.
00:27
We would go it includes negative 2 and it goes up to 11 but doesn't include it so we put a parenthesis.
00:36
So i think that's what you mean by that one.
00:38
Now your next one, let's change colors, is to look at the absolute value of x is greater than or equal to 3 and that is the set of points that are 3 and higher or negative 3 and lower.
01:05
And so if you're looking at negative 3 is less than or equal to x is less than or equal to 3, that is the set of points that go from negative 3 all the way up to positive 3 inclusive.
01:21
So it's all of these points.
01:22
So they are definitely not meaning the same thing.
01:25
This can be written in interval notation as negative 3 to 3.
01:32
This can be written in interval notation as negative infinity to negative 3, united with 3 to positive infinity.
01:48
And then your next one, again i'm not sure i don't speak spanish so you have negative 1 third x plus 2 is less than or equal to 6...
