To find the value of
that makes \( f(x) \) continuous at
, we need to ensure that the left-hand limit and the right-hand limit of \( f(x) \) at
are equal, and both equal to \( f(-1) \).First, let's find \( f(-1) \):
Next, we find the left-hand limit as
approaches -1:
Now, we find the right-hand limit as
approaches -1:
For \( f(x) \) to be continuous at
, these limits must be equal:
Solving for
:
Therefore, the value of
that makes \( f(x) \) continuous at
is:
