Chapter 4 Flashcards
What is the hole?
when a factor at the bottom cancels a factor on the top. When there is a VA there is no hole.
When there is an X for the hole, find the Y by solving
What is the VA?
when factor on bottom does not cancel out in the end. OR, all restrictions. When there is a hole there is no VA.
What is the HA?
determined by the coefficients of the a term. It describes the end behavior
What is HA when bottom coefficient is greater than top coefficient?
HA: y=0
What is HA when bottom coefficient is smaller than top coefficient?
there is no HA
What is HA when bottom coefficient is equal to the top coefficient?
HA = a/b
What is HA when bottom coefficient is smaller than top coefficient BY EXACTLY ONE?
there is a SA (slant asymptote) and no HA. divide the top by the bottom equation and do long division.
What is the depressed equation?
the simplified rational equation that doesnt tell everything about holes, HA, VA etc
