Revise how to recognise and determine the equation of a quadratic function from its graph. BBC Bitesize Scotland revision for SQA National 5 Maths.

The top part of that image is the equation itself. The bottom part is a graph of the equation, which, as you can see, is exactly the same. To be fair, this equation cheats a little bit.

Find the equation of the line of symmetry and the coordinates of the turning point of the graph of y = x 2 6 x + 4 The coefficient of x 2 is positive, so the graph will be a positive U-shaped curve.
