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

A quadratic graph is any graph which has an \(\text{x}^2\) in its equation. We draw them in a very similar way to straight-line graphs and will need to substitute values into the equation. All ...
