examine examples of inverse proportion
recognise features of the graphs of y=1/x and y=a/(x−b), including their hyperbolic shapes, and their asymptotes
recognise features of the graphs of y=x^n for n∈N, n=−1 and n=½, including shape, and behaviour as x→∞ and x→−∞
use function notation, determine domain and range, recognise independent and dependent variables
