2.14.1 Drawing Graphs - Shapes

Why do we need to know what graphs look like?

  • Graphs are used in various aspects of mathematics – but in the real world they can take on specific meanings
  • For example a linear (straight line) graph could be the path a ship needs to sail along to get from one port to another
  • An exponential graph (y=kx) can be used to model population growth – for instance to monitor wildlife conservation projects

Drawing graphs – shapes

  • Recalling facts alone won’t do much for boosting your GCSE Mathematics grade!
  • But being familiar with the general shapes of graphs will help you quickly recognise the sort of maths you are dealing with and features of the graph a question may refer to
