MTH270 - Sec 2.2 Limits

Please note that there is an error at the 3:20 mark: I wrote VA: y=0 and HA: x=0. Clearly those are swapped. I should have written VA: x=0 and HA: y=0. Additionally, there are a 2 or 3 obvious small slips (saying denominator instead of domain, pointing to the wrong value when identifying the coefficient b in a quadratic equation, and one more I can't remember).
