This example uses the basic function \(y = f(x)\). This can then be uses to draw related functions. Notice that the main points on this graph are: \(x = - 2,\,1,\,4\) Adding or subtracting a ...

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 ...
