The graph of the function, so let me try to insert the graph from here.
00:07
Here, this one will be the graph we have here.
00:10
So let me try to zoom it in bigger here.
00:14
And if we try to analyze this graph, first we see that there are two points here, because that the function is not smooth here.
00:24
So the f -pram not exist here, and f -pram not exist here.
00:33
And now we see for the first piece of the function from here to here, the slope of the function is constant.
00:44
And therefore when you see that the slope here it is increasing equal to the 1.
00:50
So slope equal to the f prime and equal to, we see it will be exactly equal to.
00:56
Here we see it should be 2 and equal to 1 here...
