In this part you do not have to sketch the graph and you may even be given the sketch of the graph to start with. For a quadratic equation of the form \(y = k{(x - a)^2} + b\), the following ...

Writing \(y = x^2 - 6x + 4 \) in completed square form gives \(y = (x ... This also gives the equation of the line of symmetry for the quadratic graph. The value of \(y\) when \(x = 3\) is ...
