So if you combine this pink part and this part on the right, if you combine both of these, you get y is equal to the natural log of the absolute value of x. Now let's think about its derivative. We already know what the derivative of the natural log of x is. And for positive values of x, let me write this down. For x is greater than 0, we get the natural log of the absolute value of x is equal to the natural log of x. And we would also know, since these two are equal for x is greater than 0, for x is greater than 0, the derivative of the natural log of the absolute value of x is going to be equal to the derivative of the natural log of x, which is equal to 1 over x for x greater than 0. So let's plot that.
