Hi dorkymichelle,

Well, I don't get what you got. I don't have a graphing program where I can show you, but here are the three functions and tables. Graph them and see the differences.

Branch [1]:

Code:`x | f(x)`

-6| 1 Closed

-5| 0

-4| -1

Code:`x | f(x)`

0 | 9

-3| 0 No reason to stop here!

-4| -7

Code:`x | f(x)`
