Math Problem Statement

draw the graph of f(x) =xx24f\left(x\right)\text{ }=\frac{x}{x^2-4}

Solution

Here is the graph of the function f(x)=xx24f(x) = \frac{x}{x^2 - 4}.

Key Features:

  1. Vertical Asymptotes: The function has vertical asymptotes at x=2x = -2 and x=2x = 2 because the denominator becomes zero at these points.
  2. Horizontal Asymptote: The horizontal asymptote is at y=0y = 0 because as xx approaches infinity, the function approaches zero.
  3. Intercepts: The function crosses the origin (0,0), which is the x-intercept as well as the y-intercept.

Tip:

When sketching the graph of a rational function, always check for vertical and horizontal asymptotes as they are critical for understanding the function's behavior.
