Here's a graph similar to what yours looks like.
00:04
And let's see if we can find these things.
00:07
Absolute minimum.
00:08
So the least a y value that this function hits.
00:12
Well, if this point right here had been colored in, the absolute minimum would be that point.
00:19
But it's not colored in.
00:22
So that means we can get close to it, but we can't ever get there.
00:26
So the y value there was one.
00:29
So we have to say there is no.
00:31
Absolute minimum because we could go to 1 .1, 1 .01, 1 .001.
00:38
We'll never get a minimum.
00:43
Okay, so none.
00:46
Absolute maximum, clearly this, tallest, highest y value.
00:51
1, 2, 3, 4, 1, 2, 3, 4, 5.
00:55
So you could say f of 4 is 5 or it's the 0 .45.
01:01
That's the biggest thing on this whole graph.
01:06
Okay, now let's just go through each point here.
01:09
A is none of these things.
01:11
Okay, can't be a local, and we already found the absolute...
