This worksheet allows you to investigate quadratic graphs given in Factorised Form.[br]Use the sliders to change the values of a, b and c and note what happens to the shape of the graph, and where it cuts the x and y-axes.
For a quadratic graph given in the form y=a(x+b)(x+c)[br]1. How can you work out where the graph will cut the x-axis?[br][br]2. How can you work out where the graph will cut the y-axis?
