Step 1: Observe the graph of f(x) and focus on the behavior of the function as x approaches 0 from the left (x → 0⁻). The graph shows that as x approaches 0 from the left, the value of f(x) approaches -1. This indicates lim_{x→0⁻}f(x) = -1.
Step 2: Next, examine the behavior of f(x) as x approaches 0 from the right (x → 0⁺). The graph shows that as x approaches 0 from the right, the value of f(x) also approaches -1. This indicates lim_{x→0⁺}f(x) = -1.
Step 3: To determine lim_{x→0}f(x), check if the left-hand limit (lim_{x→0⁻}f(x)) and the right-hand limit (lim_{x→0⁺}f(x)) are equal. Since both limits are equal to -1, the two-sided limit exists and is equal to -1. Therefore, lim_{x→0}f(x) = -1.
Step 4: Summarize the results: lim_{x→0⁻}f(x) = -1, lim_{x→0⁺}f(x) = -1, and lim_{x→0}f(x) = -1.
Step 5: Ensure clarity by verifying the graph and confirming that there are no discontinuities or jumps at x = 0 that would contradict the conclusion.
