Hi everyone, welcome to the problem.
00:02
So in this problem, we have to find d over d x, f of g x using the graph.
00:09
Okay, this is the graph.
00:11
Now coming to the problem, d over dx, f of g x is equal to f dash of g x into g dash of x.
00:34
Okay.
00:35
So let's take this as our first equal shape.
00:38
Now, equation of a line.
00:41
So equation of a line, equation of a line is y minus y 1 is equal to m into m multiplied by x minus x1.
00:56
This we will take it as equation 2.
01:01
Then slope of a line.
01:05
So slope of a line is m is equal to y 2 minus y 1 divided by x2 minus x2 minus x1 this we will take it as equation three okay now from the graph of now from the graph of g of x we will be taking two points okay so this is our g of x so we will be taking two points one point is here that is 0 .40 and the other point is here which is 40.
01:45
Okay.
01:47
So we will be taking our x1 comma y1 as 0 .40 and x2 comma y2 as 40.
01:57
And x2 comma y2 as 40.
02:00
Okay...
