Summary

This video is the next in the Analysing and interpreting graphs section of the Further Maths textbook. Having already looked at Line Segment Graphs I now take a look at what a step graphs is. Basically, it's a graph with steps and lots of circles! What are the circles all about? Watch the video and I will explain. I use a number of worked examples to help explain the theory in an easy to understand way. All with some humour too.
