Attention to detail

When graphing with a restricted domain, pay attention to the little things.

• Is there an endpoint? endpoints? ......if so, open or closed circles? 
• Is the graph dots or continuous?  
• Is zero even, odd or neither?
• Is zero positive, negative, or neither?  

Here is some attention to detail I was not anticipating.....

Did you see the ants on the sandwich on last night's worksheet?

Are there any things you would add to the bulleted list up above?  

Did you notice the ant sandwich? 

Favorite Sandwich?  Turkey......however, I am on a grilled cheese, tomato, avocado kick.
