Solution

From the uploaded image, the graph appears to depict a rational function with two horizontal asymptotes and a vertical asymptote at x=2x = -2. Let's analyze the graph systematically:

Observations:

  1. Horizontal asymptotes:

    • As xx \to -\infty, f(x)1f(x) \to -1 (function approaches the horizontal asymptote from below).
    • As xx \to \infty, f(x)1f(x) \to -1 (function approaches the horizontal asymptote from below).
  2. Vertical asymptote:

    • At x=2x = -2:
      • As x2x \to -2^-, f(x)f(x) \to \infty (approaches positive infinity from the left).
      • As x2+x \to -2^+, f(x)f(x) \to -\infty (approaches negative infinity from the right).

Correct Answers:

Based on the graph:

  • Correct:

    • As xx \to -\infty, f(x)1f(x) \to -1.
    • As xx \to \infty, f(x)1f(x) \to -1.
    • As x2x \to -2^-, f(x)f(x) \to \infty.
  • Incorrect:

    • As x2x \to -2^-, f(x)f(x) \to -\infty (this occurs for x2+x \to -2^+, not x2x \to -2^-).
    • As xx \to -\infty, f(x)1f(x) \to 1.
    • As xx \to \infty, f(x)1f(x) \to 1.
