Math Problem Statement

Consider the function of the following rational function. Identify the horizontal asymptote, vertical asymptote, and the domain based on the graph provided.

Solution

Analyzing the Graph:

  1. Horizontal Asymptote:

    • A horizontal asymptote occurs when the function levels off as x±x \to \pm \infty.
    • From the graph, it is clear that the function approaches the line y=0y = 0 (the x-axis) as x±x \to \pm \infty.

    Horizontal Asymptote: y=0y = 0.

  2. Vertical Asymptote:

    • A vertical asymptote occurs when the function approaches infinity as xx approaches a specific value.
    • From the graph, the vertical asymptote is located at x=2x = 2 because the graph diverges as it nears x=2x = 2.

    Vertical Asymptote: x=2x = 2.

  3. Domain of the Function:

    • The domain includes all xx-values except where the vertical asymptote occurs.
    • Since there is a vertical asymptote at x=2x = 2, the domain excludes x=2x = 2.

    Domain: x(,2)(2,)x \in (-\infty, 2) \cup (2, \infty).


Final Answers:

  1. Horizontal Asymptote: y=0y = 0.
  2. Vertical Asymptote: x=2x = 2.
  3. Domain: x(,2)(2,)x \in (-\infty, 2) \cup (2, \infty).
