In this problem, we have to use the definite integral to find the area between the x -axis and fx equal 8x minus 24 on the interval 2 to 6.
00:21
So first we have to find here, we have to check that if the graph crosses the x -axis in the given interval.
00:30
Let's draw this graph of this function.
00:34
So f x equal at x minus 24 if the x intercept will be if you put here y equal 0 x intercept will be 3.
00:46
Let's say somewhere 3 and 0 and by putting x equal 0 we have f x equal minus 24.
00:56
So the y intercept to be somewhere here minus 24.
01:00
So if we draw this, so we will have here, let's say this.
01:11
This is fx equal at x minus 24.
01:16
Now the interval is we have 2 to 6.
01:22
So we have to check here.
01:27
We had to check here that the graph crosses x -axis between this interval or not.
01:33
So the s, this is as that graph of f -fx...
