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 ...

All quadratic functions ... to the equation are the values of the x-coordinates of the points where the graph crosses the x-axis. Draw the graph of \(y = x^2 -x – 4 \) and use it to find the ...
