This problem is similar to Probem 6 on the Final Exam Study Guide. In that problem and the one below, you are given a derivative and asked to undo the derivative with an antiderivative.

# Final Exam Study Guide Problem 7 Solution

Problem 7 deal with approximating area under a function using rectangles. This information is covered in Section 13.2.

# Final Exam Study Guide Problem 6 Solution

In this problem you need to take a derivative in the form of marginal cost and undo the derivative to get the cost function. This is covered in Question 4 of Section13.1.

# Final Exam Study Guide Problem 5 Solution

This challenging problem requires you to find an antiderivative using substitution from Section 14.1 and the Fundamental Theorem of Calculus from Question 2 in Section 13.4.

# Final Exam Study Guide Problem 4 Solution

This is a basic antiderivative problem from Section 13.1. This problem requires you to use the Power Rule for Antiderivatives.

# Final Exam Study Guide Problem 3 Solution

This problem asks you to find a point of diminishing returns. This is simply a business term for an inflection point. This means you need to find the second derivative and set it equal to zero. To make sure the second derivative changes sign (that is what happens at a point of inflection), you need to check the sign of the second derivative and see if it really does change.

This content is covered in Question 4 of Section 12.2.

# Final Exam Study Guide Problem 2 Solution

This problem uses the same idea as Problem 5 on the Midterm Study Guide and Problem 5 on the Midterm Exam. The difference in this problem is that the derivative in part c requires the chain rule.

# Final Exam Study Guide Problem 1 Solution

The first problem on the midterm is a problem where you need to find the absolute maximum of a function. Since the function is defined on a closed interval, the absolute maximum or minimum occurs at the endpoints of the interval or at any critical points.

# Final Exam Study Guide

The final exam is less than a month away so it is time to start studying for it. If you are in the face to face class, you will take the final exam in class on Wednesday, December 7.

For online students, the Final Exam must be taken on either Wednesday, December 7 or Thursday, December 8. I will have the exam available at the same testing center you used for the midterm. If you need to change locations, contact me before November 18 so that I can contact the testing center.

Below is the study guide for the final exam.

At this point, we have not covered every single question on the final exam. However, you should be able to do Problems 1, 2, 3, 4, 6, and 7.

Over the next few weeks I will post the solutions to these problems. You can search for them on the blog posts, but is probably easier to click on Final Exam Study Guide in the Categories to the left.

# Midterm Problem 7 Solution

In this problem, you find a revenue function and calculate its instantaneous rate of change using the derivative.

This problem is similar to Problem 7 on the Midterm Study Guide.
