Making tables of numbers is cumbersome. Let’s transition to doing the analysis without a table.

What happens when both the numerator and denominator go to 0?
Consider . What is ? ________________
Consider . What is ? ________________ undefined
Consider . What is ? ________________ undefined (Well, technically indeterminate…)
Now what happens to as gets close to 1? It looks like approaches _____ as approaches 1.
Now what happens to as gets close to 1? 2 It looks like approaches _____ as approaches 1.
Now what happens to as gets close to 1? 2 It looks like approaches _____ as approaches 1. In other words:
