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 ...

The quadratic formula for a quadratic equation in the form of \(ax^2 + bx + c = 0\) is ... so the equation has no real solutions. The graph of \(y = x^2 + 2x + 5\) does not cross or touch ...
