To find the value of
that makes \( f(x) \) continuous at
, we need to ensure that the limit of \( f(x) \) as
approaches
is equal to \( f(-1) \).First, let's find the limit of \( f(x) \) as
approaches
. We start by simplifying the expression for \( f(x) \) when
:
We can factor the numerator:
For
, we can cancel out the
terms:
Now, we take the limit of this simplified expression as
approaches
:
For \( f(x) \) to be continuous at
, we need:
Thus, we set
equal to the limit we found:
Therefore, the value of
that makes \( f(x) \) continuous at
is:
