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 diagram ...

Quadratic equations are basic to algebra and are the math behind parabolas, projectiles, satellite dishes and the golden ratio.

Quadratic graphs A quadratic graph is produced when you have an equation of the form y = a x 2 + b x + c, where b and c can be zero but a cannot be zero. All quadratic graphs have a line of symmetry.
