PLEASE HELP
How can you identify the asymptotes of a rational function simply by looking at its graph? What inaccuracies might be introduced into this process? What might be a more accurate way to find a function's asymptotes? Give examples of at least one rational function with asymptotes in your explanation, and identify the asymptotes.
