Sooo.... I am one of the many who believes that they did not do well on their test. I completely forgot that section thirteen - four even existed and I think this is what made me bomb it.
Alright, here we go.
Rules for fractions.
If the top degrees equals the bottom degrees then the answer is coefficient.
If the top degrees is bigger than the bottom degrees, the answer is plus or minus infinity.
If the top degree is less than the bottom degrees, the answer is zero.
If those rules don't apply, use a table and figure out what it is approaching.
lim r^n = 0 if |r| < 1
r = number n = infinity
Example lim
n = infinity = (.99)^n = 0
|.99| < 1
