A cubic graph is produced when you have an equation of the form \(y = ax^3 + bx^2 + cx + d\), where \(b\), \(c\) and \(d\) can be zero but \(a\) cannot be zero. Cubic graphs are curved but can have ...
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.
