I was reminded by Miss. Thuylinh Duong that one of our homework exercise may contain an error. It is number 9 in section 2.5 as in below.

Suppose the graph of f is given. Describe how the graph of each function can be obtained from the graph of f.
(a)
y = f(2x) − 3

According to our textbook, it should be "shrink horizontally by a factor of 1/2, then shift down 3 units". I have contacted the WebAssign customer service and am waiting for their comments.

How to purchase WebAssign access code

## Students

For most classes that uses WebAssign, each student will need an access code. Note that this access code is not a password and is not required to log in to WebAssign. Access codes can be obtained in three different ways:

• Purchase a textbook that is bundled with an Access Code Card, and enter the code after logging into WebAssign
• Purchase an Access Code Card separately at your bookstore. For this option, before going to the bookstore, find the matching prefix for your textbook title to ensure that you purchase the correct Access Code Card. Enter the access code after logging into WebAssign.
• Purchase an access code online after logging into your WebAssign account. A credit card or PayPal account is needed for this option.

If a student drops a class, a refund can be requested within 14 days of the online purchase date. Please contact usand include the transaction ID from the receipt or the name of the class to refund. Note: WebAssign cannot provide refunds for printed textbooks or access code cards purchased from your campus bookstore.

If you have already purchased a textbook and do not wish (or need) to use ebook in WebAssign, I would suggest you to check with staff in our bookstore and ask them if you can get some discount (although I really doubt that, but it is no hurt to ask) to buy access code alone just for reach the homework.

I have tried WebAssign's online purchase and had no luck got opt out the ebook. That is why I think you might want to try our bookstore instead.

On the other hand, if anyone knows how to buy access code in a cheaper way, please share your experience with all of us. You may email or talk to me with you suggestion.

Thank you all!
