Right, in question 110, we're supposed to find the average value of the function, y equals x squared, on the interval from negative 1 to 1.
00:10
In the readings, you can find the formula for the average function.
00:18
And so this is a, this is b, and this is f of x, of course.
00:25
So what we end up having is a, b.
00:29
The average value is equal to 1 over 1 minus negative 1 times the integral from negative 1 to 1 of x squared to x.
00:55
All right.
00:58
This is going to be, this is 1 half.
01:05
Now, we saw before that the the area under x squared, this was in problems like 98 through 103.
01:21
That's going on with this pen right now.
01:23
All right.
01:24
So we were told that the integral, right, from zero to one of x squared, dx, is equal to one third...
