Is answering an assignment's questions using the class textbook considered plagiarism?

My question is simple.



My professor gave us an a simple assignment (few questions), and all the answers are found in the textbook and his slides.



Note: this is a grad class



Now, if I used these answers directly, would this be considered plagiarism?Is answering an assignment's questions using the class textbook considered plagiarism?
As long as you cite the source, give credit to it (book/author), you should be fine.Is answering an assignment's questions using the class textbook considered plagiarism?
You're asking this question as a -graduate- student!?!?



Do yourself a favor, save some tuition money and a good deal of embarrassment and drop out now. If you can't complete a simple assignment without plagiarizing from the text, you clearly have no business in a graduate program.
