Rational functions and graphs – Further Pure Maths 1

Candidates should be able to:

  • sketch graphs of simple rational functions, including the determination of oblique asymptotes, in cases where the degree of the numerator and the denominator are at most 2 (Including determination of the set of values taken by the function, e.g. by the use of a discriminant.
    Detailed plotting of curves will not be required, but sketches will generally be expected to show significant features, such as turning points, asymptotes and intersections with the axes.)
  • understand and use relationships between the graphs of \(y = f(x) , y^2 = f(x) , y = \frac{1}{f(x)} , y = |f(x)|\) and \(y = f(|x|)\). (Including use of such sketch graphs in the course of solving equations or inequalities.)
