Graphing a Rational Expression - Problem 11 516 views
If we know key features of the parent graph of f(x) = 1/x , then we can use transformation rules to graph other rational functions. Numbers added or subtracted in the denominator represent a horizontal shift, and numbers added or subtracted outside the fraction represent a vertical shift. Don't forget to transform the asymptotes and key points as well. If the function that you're asked to graph isn't in a form where transformations make sense, try using long division to change the form in which it is presented.
