Okay, so just so you know, the average cost per unit, just like this fancy c bar of x, is going to be receive x function divided by x or over x.
00:17
So the average cost per unit is going to be the function that you were given, all over x.
00:29
Now to find that minimum, we need to find the derivative of this function we just created.
00:35
So we will probably have to use the quotient rule to help us to find that derivative.
00:42
So the derivative of our average value is going to be represented by the following.
01:21
So here's my derivative.
01:26
Now to find critical points and help us find minimums, maximums, whatever, we need to set this equal to zero and to solve for critical points.
01:42
So just notice that we just worry about the numerator...
