Step-by-step explanation:
The marginal cost function is:

The marginal cost for 100 books is:

The difference is:


The relative error is:


5,383,000 because you started with 5,382,619 and wanted the 1000 spot that is the number 2 but the number to the right is a 6 which in the order of rounding 6 is greater than 5 so the rule is. Greater than 5 round up.
The area equation here is:

That means that the area depends on the width measurement of the rectangle.
To graph a quadratic function you have to see if the parabole is positive and the transformations, in this case, are positive and have a multiplication by two, which means that the graphics in x=1 and x=-1 will be y=2
Finally, you can conclude that there, you have a relationship between the area and the width of the rectangle because is a quadratic relationship and the area will increase in a quadratic form according to the increase of the width.
