Graphing Techniques - Asymptotes and Discontinuities

Graphing Techniques - Asymptotes and Discontinuities

Find the equation(s) of the asymptote(s) for each of the curves below.

  1. \(y = \frac{1}{x+3}\)
  2. \(y = \frac{1}{(x-2)(x+3)}\)
  3. \(y = \frac{x^2+3}{x-1}\)
  4. \(y = \frac{1-x}{2x+1}\)
  5. \(y = \frac{2x^2+x+1}{x+2}\)
  6. \(y = \frac{x}{x^2+x-3}\)
  7. \(y = \frac{x^2-2x+1}{x^2+3}\)
  8. \(y = \frac{2}{x^2+6}\)
  9. \(y = \frac{x^2+x-4}{x+3}\)
