Hi there.
00:01
For your question, i only see this part on my screen, so there is no any given graph here.
00:08
Let me just explain when the integral value is positive, negative, or zero.
00:13
So if the graph of the function, let me just graph the function here, let's say this is the x and y axis.
00:20
This is x, this is y -axis.
00:23
For example, we have the graph of something like this one.
00:26
Let's say this is a, b, and c.
00:28
So let's say this is the f of x.
00:31
So if the shaded region is above the x -axis, which is this green part, so the integral value here is from a to b, the f -of -x, the x -the -s, so the shaded region is above the x -axis.
00:45
So is equal to above the x -axis.
00:49
So that means the integral value here is greater than zero...
