Solution
Solution Steps
Step 1: Determine the left-hand limit as x approaches -1
To find the left-hand limit of \( f(x) \) as \( x \) approaches -1, observe the value that \( f(x) \) approaches from the left side of -1. From the graph, as \( x \) approaches -1 from the left, \( f(x) \) approaches -3.
\[ \lim_{{x \to -1^-}} f(x) = -3 \]
Step 2: Determine the right-hand limit as x approaches -1
To find the right-hand limit of \( f(x) \) as \( x \) approaches -1, observe the value that \( f(x) \) approaches from the right side of -1. From the graph, as \( x \) approaches -1 from the right, \( f(x) \) approaches 2.
\[ \lim_{{x \to -1^+}} f(x) = 2 \]
Step 3: Determine the limit as x approaches -1
The limit of \( f(x) \) as \( x \) approaches -1 exists only if the left-hand limit and the right-hand limit are equal. Since the left-hand limit is -3 and the right-hand limit is 2, the limit does not exist.
\[ \lim_{{x \to -1}} f(x) \text{ does not exist} \]
