Question
Use properties of limits and algebraic methods to find the limit, if it exists.
lim x→−3 
x2 − 9
x + 3
Step 1
We want to use properties of limits and algebraic methods to find
lim x→−3 
x2 − 9
x + 3
.
Note that the function is a     function. The numerator and denominator are 0 at
x =
 
 
,
and thus we have the indeterminate form      at
x =
 
 
.
We can factor
 
 
from the numerator and reduce the fraction.
lim x→−3 
x2 − 9
x + 3
=
lim x→−3 
 
 
 
 
(x − 3)
x + 3
  =
lim x→−3 
 
 
 
 
  =
