Now you are ready to try on your own. You have been performing first and second derivative tests for three weeks. Now you are sketching the graph in addition. Do not use your graphing calculator!

• No, I am probably going to use my graphing calculator and then regret that decision when I have a quiz/test where I am unable to use it
• Yes, I understand and will not use my graphing calculator
