In this lesson I show you how to find the axes crossing points (i.e where the graph intercepts the x and y axes), how to sketch parabolas and also determine the coordinates of a vertex (aka stationary point/turning point) using two different methods: line of symmetry 03:21 and completing the square 06:26. General tips for sketching 09:26. This lesson is suitable for extended GCSE/IGCSE and AS/A Level Maths.
