All right, for this problem, we are given a graph and asked to find some things about it, the absolute max and min and then any local maximums and minimums.
00:14
Looks like you had the absolute maximum, correct? so the absolute maximum highest point on the graph, of course, is at a height of five.
00:22
So the absolute maximum.
00:24
And this one is looking for the values.
00:27
So don't put the x value, put the actual maximum value, which is five, which it looked like you had that one correct.
00:34
Checks was a weird, a different looking check, and i assume it's because it's partially correct.
00:39
All right.
00:40
The absolute minimum.
00:41
What's the lowest point we get to? well, this one goes down to a height of two, but this one keeps dropping.
00:46
But notice it goes to an undefined point.
00:49
So as i get closer and closer to x equaling seven, this gets closer and closer to y equaling one, but never actually gets there.
00:57
Okay.
00:58
We are not guaranteed a maximum or a minimum, absolute max or min, unless we are.
01:03
On a closed continuous curve.
01:06
This one is not continuous and actually approaches an endpoint.
01:11
And since that would be where the lowest point is and we can get closer and closer, but never quite get there.
01:16
We have to say that this one does not exist.
01:19
There is not an absolute minimum value on this graph.
01:22
All right...
