Rational functions and graphs

What this topic asks you to be able to do

  • sketch the graph of a simple rational function whose numerator and denominator each have degree 2 or less, including working out any oblique asymptotes
  • understand how the graphs of y = f(x), y² = f(x), y = 1/f(x), y = f(hx) and y = f(x + h) are connected to one another, and make use of these links
