Now, the first thing i'll point out is 1, 2, and 3 each have the same answer.
00:05
And that answer is negative 1.
00:08
And the reason for that is when you look at the graph, and see, they have the graph here in blue, at x equals negative 1.
00:17
Whoops, i was given the x value.
00:19
That is not the correct answer to 1, 2, and 3.
00:22
The correct answer is actually 2, because as you look at the graph at x equals negative 1, this curve goes up.
00:32
At a y value of 2, both on the left side and the right side.
00:39
But we have a closed dot up here at y equals 3.
00:44
So the fact that your ordered pair is negative 1, 3, that's your correct answer to number 4 is 3.
00:51
So again, the left side is approaching a y value of 2, and right side is approaching a y value of 2.
00:57
So the limit exists, and we say the answer is 2.
01:00
So then on number five, we're looking at one now.
01:05
So what's happening here? we have the left side is approaching three, but on the right side it actually jumps up here to four.
01:14
See that ordered pair is one, four there.
01:18
So i need to do each one of these limits...
