- 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
- Show significant features of rational graphs, such as turning points, asymptotes and intersections with the axes.
- Determination of the set of values taken by the function, e.g. by the use of a discriminant.
- Understand and use relationships between the graphs of y = f(x), y^2 = f(x), y = 1/f(x) , y = If(x)I and y = f(IxI)
