BTW, here is a cool working graphing calculator that doesn't need a download, https://www.desmos.com/calculator
For our purposes for this week's questions, http://www.meta-calculator.com/online/ is a great option. Select graphing calculator, simply type in your equation (start with y=) and click the table tab to see a complete table of values. Awesome FREE stuff.
Anyway, good luck with the tough questions this week. These problems are due on Friday December 13th.
